Midly important. I wouldn't have bought my car if it got 10 MPG, but I'm happy that I get more than 30 on the highway and 25 around town.

Only really irrelevant if the service period and purchase price are similar. Just means that depreciation ~= 100%. I doubt it would amount to much monthly difference in your scenario, but its a large factor when people are looking at new tech like hybrids.

Agreed.

The purchase price was determined based on his current (smaller) payment, monthly fuel price, and average monthly repair costs. I.e. one year's worth of repairs/12. This resulted in a monthly budget. We assumed some smaller monthly repair cost being that the car would be new and have a warranty for the first few years, calculated and subtracted the reduced fuel costs of a new car. Then we estimated and subtracted insurance and were left with the monthly budget for a car payment. We then plugged the monthly car payment budget into a "loan buying power" calculator and *poof* the purchase price limit for a new car assuming it got at least the mileage we assumed.

I drive around 60 miles a day to work and my truck gets 15-18 mpg, so lets assume I'm burning through 16 bucks/day in gas plus turnpike tolls. I used to have a commuter car plus a truck but the truck would sit for months without being driven and was in the way as it would sit in our driveway. I sold the commuter car and truck (truck wasn't big enough for the family), and bought another truck with a crew cab. I also carpool so I drive every other week. With having only one vehicle, I save probably 4-5k minimum off the cost of a daily commuter vehicle, plus the insurance and maintenance costs and I've freed up space in the driveway. The tradeoff is I get mediocre mpg with it and gas really isn't getting any cheaper. I imagine I'll keep this truck for a few more years and then move up to a newer crew cab truck that gets mid 20's or higher for economy.

EDIT. My commuter car was a jetta markIV that we couldn't use as a family car due to size issues and my truck was a 97 f150 extended cab that my kids were outgrowing. There wasn't enough room to ride comfortably in the rear seats for my two older kids, especially with a car seat in it and my mpg in it was horrible as it was the first year for the 5.4 liter.

Often such MPG braggers are way off, and are actually getting much lower mileage.
Yeah even among cars that can consistently get great gas mileage there seems to be this tendency to exaggerate. Had a friend with a fit that had an immediate fuel economy gauge that would often tell him he is getting 60 MPG and would sustain an average of around 40MPG, cept when you did the numbers it was really around 33 MPG.

I keep all my fill ups in an Excel spreadsheet so that I can keep track of this. This is helpful in seeing which gas stations give poorer mileage (probably from excessive ethanol) and when my vehicles decrease gas mileage (showing me the need for repair/replacement of something). Here are the numbers for my 3 vehicles:

17.5 mpg: 2001 Mazda Tribute
21.5 mpg: 1992 Mercury Cougar
34.2 mpg: 1998 Saturn SW2

I also have a cell that shows how much I've saved by driving my SW2 instead of my Cougar. Since March 2nd (when I bought it), I've saved $278.

Anybody who does not take into account the total cost of ownership of their primary transportation. is a fool.

If your car is a daily driver, then fuel economy is an important piece of the puzzle.

Sure, but anyone that cares about what they drive and chooses to drive a piece of shit and be miserable about it to save some gas is a fool as well IMO.

That's strange. I didn't know a Ford Fusion, Honda Accord, and Toyota Camry qualify as a POS that's miserable to drive. With a 4-banger, all can get 35+ mpg on the highway (or a bit less, depending on the year).

Also, I've heard from many Honda Fit owners how much they love their cars and how much fun they are to drive. Even Car & Driver said it was a fun car to drive.

We had a couple trips on the freeway where my wife was driving that we got around 35-36mpg but my last couple tanks have been over 40mpg average.

Nice numbers. Do you use a program to generate those numbers?

I like tracking the cost/mile number as well. My cost/mile decreased from $0.163 to $0.103 going from the Cougar to SW2. My gas must be cheaper here (SW Missouri) since your gas mileage is better than mine.

Of course, my SW2 is so miserable to drive, that I don't know how I live with myself. I really should've bought one of those plush F-150s instead

If your car is a daily driver, then fuel economy is an important piece of the puzzle.

If you plan to drive 200,000 miles, then at 10MPG, that's 20000 gallons of gas. At 20MPG, that's 10,000 gallons of gas. At 40mpg, that's 5000 gallons of gas.

As you can see, there are diminishing returns as fuel economy increases.

insurance + gas + purchase price for me for 200K miles (or about 25K per year for 8 years) minus predicted/projected value of car afterwards when it gets sold or traded in....

20000 gallons vs 5000 gallons over the life of the car adds up to a LOT of money .... especially when gas is fvcking expensive, (currently over $4.25 in Chicago area.)

If Gas averages $4 per gallon over the next 8 years ... then we are talking about $80,000 vs $20,000 .....

That is HUGE.

You are going to talk me out of my Ranger FX4 Level II and into a Mercedes/BMW/Audi Clean Diesel.

Please.

Stop.

Or, just don't worry about it and drive. I think its important to run the numbers every once in awhile as it can be a valuable tool to help determine if you have car issues, but running your numbers every time you fill up is just anal. Give it a rest man, its just gas in the car, you aren't curing world hunger or anything.

:| Never said I was.

Part of the reason I bought this car was because of the city mileage so I want to make sure the car is getting the mpg claimed by the manufacturer. It isn't difficult to do and I did it manually with my last car every time I filled up. I never saved it anywhere or logged it but with this app it is so easy to log and track that I've gotten in the habit. Plus, when people ask me what kind of mileage I'm getting I have solid data to back it up.

It's just money out of your wallet. Money that a lot of people would rather spend on something different. You could be saving a decent chunk of change if you drove a minivan instead of a 5.4L V8 truck.

You might want to spend more money of fuel to drive a truck instead of a minivan, but that doesn't mean that's dumb care about fuel economy. Considering this stuff carefully can mean a pretty big difference in your disposable income.

Cost is only one factor to consider.
It's up to you to decide what you want.

I was just making the point that too many people completely negate looking at real costs and instead only look at what the "monthly payment" will be.

If the ranger is worth the extra fuel costs over the years, then go for it!

Fuel economy is one important factor to consider, but it it obviously not the only thing.

If it was, then everybody would be driving little electric scooters.

Sure, but you're also talking going from 10mpg to 40mpg. More realistically you're normally looking at going from maybe 22-23 to 30ish

My car will cost about $24k in gas over 8 years at current fuel prices. A much more unpleasant econobox getting 30mpg would be $17k over 8 years. $7k isn't chump change by any means, but I'd much rather drive the nicer car with enough power to safely merge, etc in Chicago.

Yes, see, you did the math, and you determined the sacrifice was worthwhile.

And there are lots of people who had very inefficient vehicles back when gas was cheap who went crazy with green and got shitty little 40mpg+ 4 bangers/hybrid drive vehicles as soon as the gas spiked to $3 or $4 the first time.

10 to 40 MPG is not common, but, MPG needs to be a factor in the "is it worth the price to me" factorization process before purchasing a car.

Well, to me they are. They do absolutely nothing interesting and I find nothing fun about driving such cars. Sure, maybe a Fit is fun to drive when compared to a Yaris or whatever. Both are slow as shit in my opinion and totally uninteresting.

If you enjoy driving a Honda Fit, great. You can be satisfied and get good gas mileage. I'm not criticising that. What I would think is foolish however is is you felt like I do that all those cars that you mentioned are slow soulless people movers and still drive one simply to save money on gas.

Some people like driving. Most don't. If a car is simply a tool to move you from A to B then yeah, mileage should be fairly high on your list of what you need in a car. I really like to drive (and need a reasonable amount of capability in terms of seating and interior room) so I'll happily get 15-16 mpg to drive what I want.

Which is currently a 300C SRT8 and a GX470, so yeah I am not a typical car buyer but I really think it's dumb to drive something you hate, espcially if you have to drive a lot. It's like buying cheap shoes or a crappy mattress to save money.

I love driving for the most part. Unfortunately, the type of driving I do 99% of the time is going to and from work or errands on the weekend with my wife and our son.

I certainly don't hate the Camry but I will acknowledge that it is pretty much an appliance. Still, I take pride in my cars so I keep it clean, maintain it and enjoy it for what it is.

If I want fun I'll take the 1100cc Ducati I have in my garage. If I want comfortable, economical and practical I take the Camry.

Christ, how do I keep getting sucked into these utterly pointless debates.

I take it into account, but I drive less than 10k miles a year usually, so it isn't a HUGE factor. I won't get anything with super low mileage, as in below 20 combined. My latest car is 25/32, iirc

Sometimes people have to do what they have to do

I see where you're coming from now. I like to drive down curvy roads or back-country roads, but I don't do that too much. 80% of the time I'm in the car, my cruise is set to 65 mph. For me in that situation, I wouldn't get much more enjoyment out of an SRT8 compared to my SW2.

I actually enjoy driving my Saturn SW2 more than my Mercury Cougar even though the latter has a 5.0L (hence the gas mileage problems). The manual transmission certainly helps, and it actually accelerates and corners well for an econobox. I do think it's more fun to drive than my parents' Camry, although that wins out in the comfort category.

I rather enjoy driving my Del Sol, though admittedly sometimes I think about swapping the engine out for something with some more spunk - something like a K20. It's not bad though, as I have a close ratio transmission and about 170HP in a relatively light car.

It's not unreallistic to get 40MPG out of a small car with less than a 2L engine and a manual transmission. My mother-in-law gets 37 out of her 90's Civic with an automatic, and cars like the Civic VX are rated 43 city / 50 highway because they have more efficient (lean burn) engines.

I'm forced to drive a relatively economical car because I'm a poor college student that, out of necessity, needs to put about 20,000 miles on my car each year. Compared to the F150 I used to drive (17mpg on a good day) I'm really able to have a lot more fun on that money - things like vacations with the wifey, theme parks, computer parts, etc. I save approximately $2350 per year in gas alone in a car that cost me $2000 and has been reliable and relatively fun. It has a t-top, the back window goes down, and I put an aftermarket sound system in that sounds great. If I had a more limitless budget I'd probably still drive a small car, but it would be something more like a Lotus or an S2000.

I dont believe in new.. recent car mag just did the top 5.. honda accord, toy Cam, ford Focus? Chevy mal, mazda something.. they took the Silhouette of them all and they where all the same damn car.. HP, 1/4 mile times etc.. where almost identical.. I prefer a car that stands out, good or bad.. hence i drive older cars (most of the time). If you really like cars you dont own just one.. I have a driver (2 actually) a 06 PT Cruiser (tried to get something slightly different, get drove the least, only has like 24,000 on it) gets ok mileage in town, so-so on highway.. 24-28.. a 04 caddy CTS-V that i drive for comfort.. a old 87 vette i drive for fun (surprisingly with the 4speed +3 it gets almost 30MPG at 75) and also have a 96 sebring convertible for fun.. along with a 02 Ford Expedition for snow. All had problems when bought (except the PT) so you total the price of them all up and i have 1 NEW CAR in value and a HE!! of a lot of fun in cars.. since i didn't pay much for um i carry liability and can afford um too.. (helps that i haven't had a car accident in my life that i caused..did i just jinx myslef?)

take pride in whatever you drive.. enjoy it.. be it clunker/junker or new.. life is to short to worry about the other guy.
