Just thought I would give a little update.
It has now been about a month and over 1300 miles since we bought the car. We have had the new OEM wheels and tires for about 300 miles now. Wow! What a difference. I really encourage anyone who doesn't think that the tires/wheels make a difference to try it for yourself. It's easy to become accustomed to how your car feels. Since I knew what the car should feel like, steel wheels with no brand 175mm tires really made the car feel like it had concrete blocks for tires. It now coasts and feels like it should.
While the car was up on the lift getting the new wheels put on, I noticed that the transmission was leaking pretty badly. That prompted me to move the transmission work up to the front burner, so I found a nice used transmission with 84,000 miles on it. I picked this transmission over some specimens with lower miles for a few reasons:
1) It came from a car with a high LMPG of over 67.
2) The case has been opened before. Since it is unlikely that any synchro work would have been needed on such a gently driven car at less than 84,000 miles, it is likely that the ISB has been replaced. That corroborates well with the high LMPG, as that likely implies above average use of regen.
I will be doing the work with the help of a friend. Originally I had planned on sourcing another worn out transmission to rebuild at my leisure. I will keep the transmission I remove and rebuild it at some point.
As it turns out, the Check Engine Light was burned out. As I posted in the Problems and Troubleshooting forum, there were several codes, all of which were LAF O2 sensor related. So I'll be ordering a new O2 sensor shortly.
After driving both cars back to back several times, I have noticed that this car does have a bit less power, especially below 2800RPM before VTEC engages. Hopefully the new O2 sensor will help alleviate that. I still plan on doing a compression check at some point.
Something I'm very happy to report is that the engine has not used a single drop of oil so far in the over 1300 miles we've had it. It's still right smack dab in the middle of the full mark/circle. That leads me to believe that the rings are still good.
So all told, we are still at less than $4000 total cost of ownership, even including the new wheels and new clutch that will go with the used transmission. Still extremely pleased with the purchase, and with these things out of the way we expect to get at least another 100,000 miles out of the car without any major problems.
