Well the insurers are sorting it now. I can't see it not being a write off, assuming there's no structural damage (which there probably will be after such an impact) it needs a new rear quarter, rear bumper, boot lid, front bumper, bonnet and both wings at the very leat
Basically, I came off junction 8 of the M6 in the wet. It's a slight long right hander that goes over the motorway. Was doing about 60-65 just cruising along round the bend then suddenly the back end flicked out without any warning. I kept my foot in and tried to pull it back but it happenned too fast. Went drifting sideways for a short time before hitting the concrete wall front nearside on at what must've been about 50-60. Bounced off that and went backwards hitting the concrete wall the other side on the rear nearside. Pushed the car out of the way, checked it over, started it and drove it home slowly!
I'm honestly not 100% sure what happenned to provoke the back end to go so suddenly. I may well have hit standing water but I was a bit flustered to say the least to have a look around. I was not speeding but it's perfectly possible and likely that I was going too fast for the situation otherwise I don't think it would've happenned, or at least I would've had more time to react.
