PROS Upmarket image, smaller scale Low CO2 ratings Good resale value There are plenty of reasons to like the Audi A1 Sportback: it has five doors making it a more practical choice over the standard A1 hatchback, while it's still one of the most premium-feeling cars in this sector. It also gives Audi the chance to challenge the MINI Clubman as a viable five-door small car. With that premium feel comes a more premium price tag, and the Audi A1 Sportback is one of the more expensive choices in this class even as a used buy.
