Hi guys am thinking about purchasing a 2006 Audi S4 with 41,000 km for $35,000 CAD. I am wondering if there are any major issues I should look for before giving the guy the money, if I take it into a Audi dealership to get them to look at it is that enough? What are replacement parts like? are they ridiculously expensive?

Do you guys know of any aftermarket kits that can integrate bluetooth into the cars stereo??

Many thanks
