Only real problem has been the clutch. IDK if they know what they are doing. Oil change every 7,000 miles, mobile 1 0w40. No tranny services. No engine work. Mods 74mm throttle body and larger fuel injectors. I have changed the oil pan which was a pain, due to the oil level sensor o-ring. I done a lot, but I have done all the work. Everything except the clutch. I think that's why she's still running. I do not trust anyone else. Except for the interior literally falling apart and me not being able to scavenge parts, I think it would run forever. As to what else I have replaced, I can't really remember everything. I bought it brand new in 2005, but just ask if I have done it or seen it I will remember.
