lol...talk to any friends (or friends friend) who you might have owned or owns the car. Go for a ride with him/her. Read overseas and local blog of the car issues and maintenance.

Then if you find the right cart, just fix a appointment at AUdi SC and bring it in for an inspection prior to agreeing to purchase. Inspection doesnt cost much, RM 80 to 300, depending SC and how thorough you want them to check.
