Getting your hands on a Caterham 620 R truly fits the idea behind Go Balls Out. These things are, put simply, ridiculously fun. Weighing in at half a tonne, with 310bhp coming from a 2 litre engine, they absolutely fly around the country roads and sound unbelievable. Put your foot to the floor on a track day and you’ll hit 62mph in 2.79 seconds. Go on, you know you want one.
