unlucky mate, but i dont think it will be a right off! - ill be surprised if it is at the worst a v23 - beyond economic repair which basically means its better for the insurers to write it off, give you the glass's or parkers value guide money for it and then give you the option to buy it back as 'scrap' and get it repaired yourself! if its guna be a write off thats the 1 to hope for!
I love the corsas understeer though, after a lil practicing it is so predictable and controllable ITS ADDICTIVE!!
Better luck next time tho! keep us informed!
