You make the problem worse by choosing a Corsa 1.2 SXi: it’s a 2 year old car, so still worth quite a bit which means a bigger potential insurance pay out. It’s seen as a sporting model so the insurance industry know from experience that these are usually driven by those with more enthusiasm than skill. It’s also a model which is popular with young people as it’s seen as cool and there’s a huge supply of modified parts which can be added. This makes it more likely to be stolen or to have parts stolen from it, especially the alloy wheels. Statistically, young drivers are far more likely to have upgraded sound systems fitted and to leave valuables in the car; this makes break-ins far more likely.

If you don’t want such a nasty shock, then do everything possible to buy an older group 1 car. You may not end up with a car which will impress your friends, but you’ll end up with far more money in your pocket to do other things with, such as saving for a really good car to buy once you’re older.

And for a 1.2 SXI you’re looking at least £2000 to insure for a first time driver.

Best Of luck with that.
