where u at? $8999 sounds real low...a fairly good condition 69k 95 850 turbo should run about $13k...don't worry about brake rotors, they should be fine. as for the undercarriage...do u live where it snows in the winter? if so, then it may be hard to find one that isn't rusted a little...u should also take it for a drive and check out the suspension, a/c unit (could be very expensive to replace, 1k+ sometimes), and tranny.....the engine and turbo and stuff should be fine (provided they didn't have a manual boost controller). if it's the exhaust u'r seeing that's rusted, just simply replace it with either an aftermarket unit (pay for it urself), or get the used car dealer to get u a new one (they should foot the bill)....oh, and on a last note, make sure it doesn't rattle...it gets tiring after a while...
