I have tried to research here but haven't been able to turn up much as to any common issues on either model.
Any help/guidance would be appreciated.
Thanks in advance!
Just upgraded from a C5 to C6 - 5th used Audi. Repair records are key if you can get them. My 03 had repair receipts in the glove box which really gave me a good idea of any past history problems. Carfax sometimes can help but it is not always accurate. But if I see no dealership maintenance records under warranty, I would be concerned. If I see multiple check driveability visits to a dealer, I'd also be concerned. If recurring electrical issues show up, another concern. Still it's no guarantee. Not all dealers are reputable, but someone took the time and if out of warranty, the money to have the dealer fix or maintain. My Acura Certified MDX was a disaster despite a clean record.
Bottom line, expect some electrical problems on any high end car - they are just complex vehicles. I wanted the 3.2 because of the mileage and my independent mech's recommendation. I'm still concerned about carbon build-up and premature Catalytic converter failure, especially after noting the soot in the exhaust pipes. But the car runs nice and I pulled the codes before I bought it.
Synthetic oil changes regularly which is why seeing dealer services gives me a higher confidence. On my 03 A6, it's every 3-4K for oil and I'm at 195K now. I'm told that the 4.2 doesn't have a sludge issue and the 3.2 is much better then the earlier v6's (3.0L is the worst).
And, depending upon where you live, check the special carfax site for Hurricane Sandy vehicles. This applies to any make used car. Big problem in the northeast. Type in the VIN and it will tell you if it has been in an area that was flooded. It doesn't mean it was damaged, but check it out much more thoroughly. I got stung on my first Audi (98) with that one - no Hurricane, but the car was under water at least up to the lower door panels. Found that out when I disassembled the seat memory switch which on that car was in the lower door panel - completely corroded inside and that just led to more surprises when I pulled up the carpet.
Very nice driving car - each model just gets better. Enjoy.
