It's worth about £600 and I think it will pretty much be a write off as I was doing 60-70mph at the time...
Got a quote saying it would be about £100 to replace the belt and find out how bad it was, then could be anything from £100-300+ on top. So thinking it might be best to just put it in my garage and SORN it for now as I can get a tax and insurance refund for the last 5-6 months. Then I can see about getting it sold for scrap or spares.
It's got 11 months MOT and the brakes and tyres were all replaces a year ago so it might have some value for spares, though I have no clue on this kind of thing unfortunately...
