Looking to buy 2016 A6 with 76,500 in metallic blue/nougat brown interior at a used dealer Wednesday if all checks out. Car looks mint and clean, but apparently dealer has been driving it around as personal car for the past few weeks it’s been there im assuming. Should I be concerned with this? The dealer has it listed at $15,500 with one original owner. I’m planning on trading in my 2013 Passat at 190k with a lot of bumps and bruises on it to make the deal a little more bearable- car comes with 6 month warranty. Is there anything I should be concerned of at this mileage? I know the water pumps have a tendency to have issues, but anything else I should look out for? And does $15,500 seem reasonable?
