I need to clear some debt now that I've finished university, so selling the E34 and looking at getting a cheapo car while I save for a newer bimmer. I'm looking at a 1985 Audi 200 Quattro Turbo, the quattro will be a bonus for the ski season and it has a new lowered springs and shocks. It has a few electric gremlins I could hopefully work out over time, rear elec windows, sunroof, climate control and automatic choke not working.

The main issue though, is the smoke. The owner states "Blows smoke consistant with valve/guide wear, under med/hard deceleration". What is this indicative of? Is it terminal?

I'll probably only keep this car for 6-12 months, and it's cheap, plus if I fix it up a bit would be quite a nice car.
