18: Audi TT
When the Audi TT came out, it was a marvelous design. The turn of the millennium ushered in new car designs. The Audi TT built upon this modern design language. The performance was also solid. The TT can handle its own on the track or in city driving. A comfortable interior earned the TT high marks for quality (via Car and Driver).
As with most Audi models, the Quattro is the way to go. The TT has depreciated quite like other luxury cars from the era. The performance can match a Nissan Z, and the cost is half of what you’d pay for a Z. Audi engineering isn’t anything to sneeze at either as the car is sharp and focused.
