+1 The older zeds have become part of the hothatch priceband recently. Although they are getting cheaper the upkeep is still the same, if not more, than what they were when they were new.
I can't wait till the younguns of today get there hands on them and destroy them as it will start to make mines regain some value as they become rarer.
It's quite evident that you should hang on to your hot hatch until you can afford legit insurance and a bit more maturity about the whole idea.
If you have dodgy insurance and have an accident they will look into it. If you crash into someone, like a young mum with a child in her car and you kill that child you will find yourself in jail getting your wrongun pounded for a very long time i'm afraid
