There's no doubt the latest A3 isn't as well finished inside or as polished overall as the previous model, but it still rates well against the premium competition, in the form of the BMW 1 Series and Mercedes A-Class. It's comfortable, enjoyable to drive, has space for the family, some punchy petrol and diesel engines and a plug-in option coming soon. It's also one of the slowest depreciating cars in the class, so we recommend you should stick it on your shopping list.
