Overall, the A1 is a darned fine car. At least, the version we’ve driven so far is, being comfortable and tidy to drive and reasonably roomy, while it should be no more expensive to run than non-premium rivals. However, while it offers a better premium small car package than the Mini 5dr, the Volkswagen Polo has all the same virtues, plus it’s roomier and has a slightly smarter interior. Oh yes, and more equipment, for a much lower price tag. So while the A1 is a very good small car, it’s hard to see what, other than those four rings on its bonnet, you’re getting for your extra cash.
