Audi TT
Much like the Porsche Boxster it was based on, the Audi TT was also a reliable sports car. Even today the TT is one of the most highly sought-after sports cars on the used market. Although there were other cars from this era that had better performance, the TT boasted superior build quality and reliability (via Hot Cars).
The TT had a lot of innovative features, and in the Quattro trim package, it’s quite the sports car. Slick styling and a beautiful interior are attributes that even a used TT boasts today. There was a lot about the car that was far ahead of its time, which is why its popularity was there from the start. The TT doesn’t always get the credit that it deserves, but it was a game-changer in 1999.
