We had a 2005 A8 that we kept until 2015. Few repairs that were fairly expensive. I am considering a 2013 CPO A6 Premium Plus 2.0 or 3.0

My question regards reliability. I keep cars a while, so I want to make sure that the A6 is a reliable car. My service writer will run the vin on anything I look at, so he can tell if any warranty claims, etc.

All advice feedback welcome
