Also, I'm curious as to what carmax means by "known transmission problems"? and what do you mean about differentials overheating? There are many members here who daily drive the z and some who regularly track it. I do both very often. Yet our cars are holding up just fine. Yes, the transmission is a bit clunky, not exactly audi or bmw buttery smooth. And yeah, vlsd isn't as good as a clutch based lsd. but there haven't been any breakdowns or drivetrain failures. I personally swapped out the crappy gearbox and diff oils for redline synthetic oils. Maybe that helps. Not sure

Regarding the rust, it's normal there will be minor surface rust underneath every car out there. it's no big deal. unless the rust was excessive and compromised the strength of the subframes, there wasn't anything out of the ordinary on your car. how bad was the rust? any pics?
