Hi Noel,

Do you mean three-cylinder? As, by 2007, the Corsa had switched to the GM O-series engine family, which were all four-valve-per-cylinder engines. Anyway, we’d go for the 1.2 four-cylinder unit, as it has a robust 80hp compared to the 1.0-litre three-cylinder’s weedy 60hp. That argument does reverse itself, though, if you’re trying to keep your insurance cost down for a learner or new driver in mind, as the 1.0 will be cheaper to cover, and so is the better choice in that specific circumstance.
