The Audi A3 Saloon is tidy in the bends, comfortable and well equipped, making it a very competitive option against its closest rivals, the BMW 2 Series Gran Coupe and Mercedes A-Class Saloon. However, the A4 is worth the extra if you can afford it, because it’s quieter and has a classier and more practical interior. Likewise, the BMW 3 Series betters the A3 in those areas, and it's also more enjoyable to drive.
