On hold to the insurance company right now. Looks like a right off! Was driving up the A13 towards London at ~70mph (within the speed limit) and someone in a white pickup decided they wanted my lane. Swerved hard and braked into hard shoulder to avoid contact and started to loose the back end. Corrected too much and lost it. At that point resumed standing on the brakes and went backwards into the central barriers.
I am fine. Totally uninjured (not even bruised). Car handled the impact very will, passenger area is totally as was before the crash. Essex Police were very quick and helpful.
Looks like I might be in the market for another car soon!
