My friend just bought a 94 Z28 with 114k. The car is beautiful! Custom paint job, and lots of other stuff.

Now, we don't have any history of the car, and it has bounced off the rev limiter a few times and backfired visciously!

Also on the freeway, at 60-65 mph, flored it and it downshifted to 2nd and the revs went up to 5,500 and the power was not there, so I let off the gas and everything was fine. What do you guys think? What kind of stuff should be looked at and/or replaced.

by the way, it is an A4, with 3.23 gears.

 

I would attempt to GET the "history".

If the car was modded, appearance wise, but not engine/drivetrain wise, I would want to know.

If it bounced off the stock rev limiter and has 3.23 gears (that's "history") then maybe its totally stock, in which case, you have some place to start.

My, uneducated, guess is that he bought it from a gypo car dealer, who bought it at auction, who got from a bank on a defaulted loan, and contacting the original owner might be a stretch. However, gypos usually don't bother to put dealer plates on the cars and one might be able to trace the former owner through the plates. On the other hand, the former owner might not be too happy about talking.

All purely hypothetical, depending upon your friend actually came to buy the car.

 

the previous owner bought it new, and just traded it in on a '00 SS. Also, didn't come with the key for the wheel locks! The 94 was on the lot for two days.

 

Now you're cookin". Get hold of the original owner and get the history.
