I just bought a 1996 Audi A6 quattro with a 120000 miles on it. I
don't know when it's timing belt was changed last? Would you recommend it
getting done at Midas or should I do it only with an Audi dealer? What other
parts needs to be replaced or checked?

Thanks

 

the timeing belt, spark plugs, I would have the audi dealership take a good over all look at the engine/condition. Thats a lot of miles, but if it was taken care of, you have nothing to worry about, just maintience.
