It was a 91TT with about 75K miles on it, not my current 95TT. I had solid compression on that motor. There are tons of Z's out there w/ problems and the owners dont know it. When I went to buy my current Z I talked to the owner and he told me how fast it was... so we go for a test drive and it was in safety boost... he thought it was normal. I bought the car and fixed the safety boost and gave him a ride in it while running at full power... he couldnt believe the car and probally regretted selling it.
