Just my 2p, but why does he want to auto-x in a Corsa C anyway? For a car to be ragged about, they're relatively expensive for not much gain. I just can't help but think he's fighting a losing battle, and if he wants to be remotely competitive, he'll need money to modify it...money which could be better spent on a decent platform car in the first place. I know of MX5s selling for ?600, which are competitive even in standard form. For that kind of money, he could keep the Corsa as a DD, and tow the MX5 to the event (avoiding road tax, MOT etc).
