Is there a cheap to insure convertible car?

Looking for a fast car/potentially fast car recommendation that's within budget and cheap to insure?

• I'm 20 years old and I've been driving a 1.8 petrol Mondeo with around 130BHP around for about 2 - 2 1/2 years now, but I'm getting bored of it and so I'm looking for something that will reignite my passion for driving. I was thinking, since getting a high powered car will likely be fairly expensive, a better option might be to get a diesel and simply remap it as this yields better performance gains at more ease. The car will likely have to be under £4000 and not above group 13 or so on the old 1-20 scale. I was thinking a Vectra 1.9CDTI 150BHP as it'll fairly easily remap to 200BHP with a few mods, but does anyone else have any recommendations?
