general problems of the 2007 Audi A4

07 s-line under 25,000 miles and just put on 3rd new set of tires. I know sport suspension wears tires quicker than normal car but this ridiculous. 1st set lasted 14,500 miles,2nd set 9,000 (I'm not a boy racer, I'm a sensible driver)1st 2 sets of tires were continentals so trying firestone now to see if they any better. Audi cars are heavy so they should accommodate tires to suit or better still, modify cars so they are less heavy. Your worth umpteen millions of pounds and still cant satisfy a lot of customers. Read the problems customers have and sort them out when u pay money for any car it should not cost you every 5 mins to keep it on the road. The dealers also think everybody is 'dumb' with all the feeble excuses they come out with. Customer care is an empty 2 words that don't stand for anything once the car is driven off the forecourt. I know lots of people who have Audi's and the complaints from them alone would fill a football stadium. Love my car but seriously thinking of changing it after the year.
