Audi TT
The Audi TT was the most influential sports car that the German automaker released in decades. The car completely changed the perception of the Audi brand at the time and it was unlike anything else on the road. The styling of the TT was futuristic and the performance jaw-dropping (via Auto Car).
Everything that made Audi vehicles great before the TT was enhanced in every aspect by this car. From the styling to the implementation, even a used TT is still a great ride. With the Quattro trim level, there are very few cars on the road that compete with the TT. The car revolutionized the sports car segment in every way.
