Buying 2006 a8l 2morrow how is the reliability
 

Im getting a 2006 audi a8l with 80,000 miles tommorrow and i wanted to no is it worth getting for 25,000 and is their a bunch of problems with this year model that i should no about b4 purchase?

No real inherent problems with that year. That's a good price for a clean title and no issues, esp if it has any added options like Premium Package for instance.
Timing belt service "should" be done by now...if not it's gonna be anywhere from $1000-$2200 depending on independent mechanic (who knows what they're doing) or dealer....home service $300-500.
If the car is basically perfect, the price is a little less than what many are asking, so could justify the timing belt service cost.
