A used Audi TT is a two-door sports car that has been in production since 1998. Used Audi TT's are an attractive choice for those looking for that sports car look and feel at an affordable price. Its two main competitors in the automotive market are the BMW Z4 and their new-for-2010 1 series coupe, as well as the Nissan 350/370Z. The TT has an almost mind-boggling number of engine choices, and can be had in front-wheel drive as well as Audi's exclusive Quattro AWD variants. The second-generation Audi TT has seven different engine options for almost all types of drivers— from the 158hp turbocharged four-cylinder found exclusively in the roadster, all the way up to the 5 cylinder 2.5 liter turbocharged powerplant of the TT RS that makes an incredible 335 horses. There's a TT that suits every driving style, from hardcore track racing to subdued beach cruising with the top down. The Audi TT has a rich history of awards under its belt too, including World Design Car of the Year in 2007 as well as resting on Car and Driver's Ten Best list for 2000 and 2001. The Audi TT rides on Volkswagen's proven PQ35 platform. Platform-mates of the TT include the Mk5 and Mk6 VW Golf and Jetta and the VW Eos. With such a large number of proven vehicles on the same architecture, it's no wonder the Audi TT is considered one of the best buys for the sports coupe shopper.
