A POOPER UPDATE -- RETURNED FROM THE SHOP
Hi-:Ho!! The Trooper rides again, Hi-Ho!!

The Damage:
$2,450, after asking to replace the EGR valve when they had the intake manifold off the car.
The Credit: $1,498 Cash-Backin' Rewards -- leaving less than $1,000 to pay outright on the card.
The Work: Replacements: Fuel-Pressure-Regulator; Throttle Position Sensor; ECT/Temperature sensor; Fuel-injector O-rings; wiring plugs for the MAP sensor and another item; heater-hoses. I replaced the MAP sensor myself at a cost of $70.
Inspection: to find a mysterious tiny oil leak from the crankcase. Used dye in the existing oil to find the leak with "special glasses". None Found!

Results: No more hard starting when engine hot or warm. No more "valve-lifter" noise. No occasional "stumbling" which most people wouldn't have sensed with the car anyway. Engine runs quiet as a -- what? -- church mouse? A kitty?

We filled the tank with gas to measure the city-driving gas mileage over the next week. I'll report back about that later. Prospects are very good!

I had bought the car when it was seven years old. I wouldn't know what it felt like to drive brand-new. But I am highly confident: It runs better now than it did 30 years ago as "brand new".

OK. The Trooper's MSRP in 1995 was $29,250. 22 years after my $8,500 purchase and 30 years after it left the factory, I have just now reached the MSRP nominal dollar expense. SOMEBODY ELSE paid the full purchase price the first time, and if they had kept the vehicle, would've added another $12,000 to $15,000 in repair and upkeep in order to get to 2024.

Is this better or worse than other strategies of car acquisition and ownership? Well, if I'd been trading in a $30,000 vehicle every six years for $10,000 trade-in value, 18 years of ownership would've cost me an extra $60,000. Others can be the judge.

Others wouldn't want to invest the time and inconvenience as have I. They wouldn't have spent $90 on the original factory shop manual. They would not have needed to wait patiently every time the vehicle was taken for repair. They wouldn't have suffered mistakes -- like failing to pay attention to the transmission warning light (in 2004), or the trial and error of finding a new repair shop (and needing to replace bad MOOG ball joints installed by an unscrupulous shop).

Others wouldn't have endured the highway "body language" of zippy little sedans whose maneuvers suggested to me "Get that old Trooper off the road!" [Nor would they have received the flattering attentions of Wranglers and Rubicons.]

In any event, it's going in for tire inflation, tire rotation, AC service and other minor needs and interests around September. Then, after the shop puts it through a brief shakedown cruise, it's going to Reno, Grass Valley and then back home --- probably 1,000 miles. Maybe in another 5,000 to 10,000 miles -- timing belt replacement. I think I could easily wait another 17,000 miles for that, given what I've seen in the way of aging timing belt anecdotes. But I won't press my luck. Reassured: the V-6 engine is a "non-interference" model, so if the timing belt breaks, there's not likely to be any damage.

You do you,BD!

Do yourself a favor when you head out on the road to Reno - AAA account, extra cell phone battery, let your friends know your itinerary,

I'm on "pins and needles" today. Soon -- before COB today -- they'll likely call me to inform that the Trooper is "ready". I was told they were test-driving it Friday. The only loose end: the engine around the oil pan "sweats" oil, so over a week, a very thin film builds up on the drop pan. Initially, I wanted them to locate the leak -- and, if not due to the rear mainseal -- to fix it. A very minor leak at the mainseal might only justify the response that "all old vehicles leak oil" --in view of the expense to repair it. But at this time, we're only going to find the leak with a dye visible with "special glasses", and then decide one way or the other.

If this proves to improve gas mileage by nearly 40%, I won't be in a hurry to put myself in the seat of a 202X RAV4 hybrid. I'm going to continue "looking into it."

I also thought it would be great to have a 4Runner hybrid, but there ain't no such animal. The other option is a Hybrid Highlander. This -- if I want to replicate features of the Trooper in its size and handling. But I should also look at PRIUS models.

Conventional wisdom, as some have used it in this thread, suggests that you must somehow avoid spending more than the BlueBook or Edmunds value of the used car. Or, that you must keep a car only until it still has "trade-in" value against a car that is maybe six years newer.

But barring engine replacement with transmission replacement and a bunch of other concurrent things, most repairs and maintenance are still a reasonable price to pay for just keeping a vehicle on the road.
The 4Runner hybrid should be out in the fall.

Another reason to wait until spring . . .

Meanwhile, I drove around locally last night. With 201,400 miles, it runs "better than new". I figure I made $1,000 in unnecessary expenditures, taking the opportunity for replacements with removal of the intake manifold. But that was still covered by the long-unrecognized credit card Cash-Backin'.

If I can actually expect a hybrid 4Runner by end of the year, it changes the ball game for choosing a new ride. If it's the first model year for such a 4Runner, Toyota has been at the forefront of hybrid technology and reported to have a new EV battery technology offering 700 miles per charge-up. No reason to wait for a subsequent model year.

NOW LOOKING AT IT MORE CLOSELY, I'M OVERCOME BY VEHICULAR LUST: Car and Driver: 2025 4Runner Hybrid

It's financially "unsound" for me, but there must be a way . . . there must be a way . .. .Wait two years for a pre-owned?

Go take a drive in the Grand Highlander Hybrid. It has the same 4 cylinder hybrid engine as the upcoming 4Runner I hear. Maybe you won't like it...

Yes -- the Highlander has been under consideration. I DO believe it will fit in my garage, but if I recall, it was fully 1 foot or 12" longer than the Trooper.

I've also determined now that my obsession with city gas mileage has been raised by a bad habit: I warm up the vehicle for as much as ten minutes before backing out of the garage. I won't go into detail as to why I do this, but it is totally unnecessary in "switch-flicking preparation" for take-off. When I got the beast back from the garage, I filled up the tank and put 5 miles on the tripmeter. Then I think I had it idling in the garage for 15 minutes or so, and drove another 2.5 miles to the gas station. I had to top up a whole gallon! But it cannot be wasting gasoline at this point: no smell of partly burned gas, no symptoms whatsoever. It's my "warm-up" that has led to these exaggerated measurements!

I may replace one more item -- the HO2S or heated oxygen sensor. If it were totally damaged, it would throw a check engine light, but it doesn't. Prevailing wisdom says to replace it every 100,000 miles. It will cost me a few hundred bucks.

After that, I could probably wait a few years before attending to the timing belt and assorted parts. By then, this will just be my "Sweet backup ride".

I could be repeating myself. The MSRP in 1995 for this ride was $29,250. I bought it for $8,500 in 2002, so including the purchase and over the last 22 years, the vehicle has cost me $122 per month for parts and repairs. I could subtract the periodic and routine tire replacement, brake replacement, fluid flushes and oil changes, but that's what it cost me.

I don't think I've done anything foolish in this matter, but I admit -- it's an orphaned model, I won't get back the money I put in over the past five years if I sell it. But it's a sweet ride.

I'm going to take another look at the Highlander tonight. There's no hurry!

UPDATE: Yeah -- I see I can find a 2018 Highlander Hybrid AWD with 52K miles for less than $32,000. A sort of Maroon-Burgundy paint job. There should be more of those available when I'm ready to plop down my ducats next spring. So it's an option. The RAV4 XLE is also an option. Even if I bought the 4Runner hybrid for cash, how would I pay the monthly insurance premium?

The engine in the 2018 Highlander Hybrid is a 6 cylinder, while the 2025 4Runner hybrid is a 4 cylinder. It's suppose to be the fastest 4Runner ever though.
