Three years ago, I bought an Audi A4 convertible, with 95K on it, Currently I have 126K on it. At time of purchase I had the timing belt done and complete tune up.
Car is still rock solid and enjoyable to drive. I have done some minor repairs: New brakes front and rear, at end of first year of ownership. I had a airbag light come on, which was the result of the kids knocking into the connector under the passenger seat on the floor.
Repleaced the seat memeory switch because the other one was stuck.
All routine maintainence. My plan is to put as many miles on this car as I can. It is my daily driver for 7 months of the year, and occasional driver when there is no snow or salt on the roads thru the winter.
