Which used Mercedes A Class hatchback should I buy?
There are plenty of engines to choose from, and if you want a petrol unit, you can choose from a 1.5, a 1.7 and a 2.0. The 1.5 is refined and never feels out of its depth, so it's perfectly adequate for the car. This makes the 1.7 largely pointless, but the 134bhp 2.0-litre provides some extra performance.
There's also a turbocharged version of the 2.0-litre, but it isn't that much quicker and it doesn't feel like a proper 'hot' version.
