Yesturday aome muppet came round a corner on the wrong side of the road and completly smashed up my car. My car was towed away after hours of waiting and he has not yet admitted liability, it was ocviously his fault but I don't have any witnesses am I likely to be able to win? Also my car has some mods which I stupidly haven't declared back box and wheels will this mean that I wont be able to cliam or will his insurance not pay out? Cheers
