Ya I saw your VW on club4ag. Looks really nice
If im not mistaken, you live in california? Rust over there isn't too bad right?
Just go and trust your instincts from being an experienced car owner as to the various sounds coming from the engine at idle, turning, braking etc. You know the drill etc. A "well used" 86 will probably have worn bearings, so listen for sounds from the rear. You should inspect all the rods in the back of the car, check if they are bent. (loss of control in a drift ---> into a curb)
