The Polo is a huge seller and it isn't hard to see why. It's a great all-rounder – smart and roomy inside, comfortable to sit in and good to drive. And while it’s pricier to buy outright than some of its rivals, that’s largely offset by competitive monthly finance rates and strong resale values. However, hybrid rivals offer better fuel economy and you need to pay extra for some of the modern safety kit rivals come with as standard.
