I've just been to the garage to get some stuff out of the car - head unit and a bunch of other crap - before the insurers pick it up. The guy did indeed just charge me £35, which seems a bargain. As said, the engine won't turn over and he listed a few things that could be down to - timing bolts, con-rod, etc - but said it's most likely he insurers would look to just replace the engine entirely. He said an engine would probably cost £2k+ plus labour plus VAT... The carpets are soaked so they'd need replacing and the brakes look all rusty, so they'd probably need something doing, I don't know. He said that the rule of thumb he's come across is that if the cost of fixing the car is over 60% of the value of the vehicle then the insurers will write it off, and when the car is probably only worth £4k, give or take, a write off seems likely.
He showed me where the intake is. It's low on the passenger side, which fits with the road being heavily cambered in that direction and the water being deeper on that side.
Right. Now I work from home and wait for the hire car to get sorted.
As far as insurance and NCB goes... I'm only a named driver, and my wife is the main driver. Direct Line do NCB for named drivers, so would that mean this will only nuke my NCB or will it affect he whole policy?
