Audi A6 Reviews

Just an absolutely fantastic car. The technology is superior to Mercedes and Infiniti (both I have owned). Fun to drive. The V-6 engine has a supercharger which puts out an exhilarating ride without any turbo lag.
This has by far been the best car I have ever owned. It is extremely smooth to drive and hardly makes any noise even at highway speeds. Not only this, but the A6 has been a very reliable car. It is now 4 years old but it still runs and looks like new. So far. the only issue was I needed to have a bulb replaced in one of my daytime running lights. It ended up only costing $35 and took 30 minutes...
Bought my 02 Audi from a lady who lived South of Denver. Got a great deal for the car. I love the 6 speed manual transmission. Excellent purchase of 150. for the extended warranty for 3 years. I saved me $$$. The only major problem that I have had is the clutch went out last year(a piece was broken inside) ouch!! 3400. to replace it. Other than that it has been a dream car to own
