help - a friends buying golf, what to look for?

I have a friend that is looking at a couple of golfs under $8000 at the moment, which range from a 92gti to a 95 stock.
he asked me to help check them out, can you guys give me any pointers at to which areas to look for, kms on engine etc etc

any advice would be much appreciated!

Try and get the latest model possible . Also stick with GL Golf . Vastly better than the CL
