It looks like a money pit to be honest and insuring it with the rs engine would be crazy money. That kit looks thrown on to be honest-and the passenger wing is a diff colour-probably a lot of tales under that kit waiting to be told. If you had access to a workshop why not have a look tho its better to spend a few sponds on that than be out drinking cans etc.
You'd want to change the engine back to original to save hassle with insurance and police , sell on the rs turbo gear and budget for a full respray+Wrc bumper to tidy it up. But anything is possible if you do it right. Whats he lookin for it?
You'll probably find a better rep for sensible money when you consider wat needs doing to that one.
Oh and the whole rep debate is raging on here at present
