This second-generation Audi TT might not have been quite as iconic as the first, but it was a far better all-rounder. Its sharp styling clothed a beautifully crafted interior, with two small rear seats suitable for children and even the practicality of a hatchback boot lid. Combined with the option of Audi’s famous quattro four-wheel drive system and a range of punchy turbocharged engines, that’s made it perennially popular, and today a used Audi TT is a splendid buy.
