Will the A6 last?

I found a 2008 Audi A6 3.2 quatro for $16000. The only problem is that it has 92000 miles on it. I thought it was a good buy but I wanted to see if it was worth it. It's in excellent condition. Can anyone tell me if it will last me a while with normal maintenance? Or will I have tons of problems out of it? Feedback is appreciated!! Thanks!
