Yesterday the 250,000th Audi TT came off the line at the Györ, Hungary plant. The yellow model in question was one of the 3.2 liter 6-cylinder coupes producing 250 horsepower. The first Audi TT came off the same line way back in 1998. In that time 165,000 coupes have been produced and 85,000 roadsters. Now when's the new model coming out?
