I just saw this thread for the first time..... OP, I'm very sorry to hear about your situation.
10 weeks old and a POS telstar takes away all your enjoyment of buying and owning a brand new car
.
It's a real shame that the insurance isnt going to write it off.
I know it will sound dodgy to everyone reading, but if I was you I'd get the thing repaired (be really picky with the end repair) and then sell it... not telling the unsuspecting buyer that it's been in an accident. (flame suit on... buyer beware folks, dont get angry at me)
Flog it off and go buy another car (like a dealer demo or something). I dont care how good a repair the insurers do, it will never be the same again. They can bend metal back into shape (and be weaker in the process) and change bits and pieces, but how do you really know everything is as it should be? With sensors and fancy safety equipment in modern cars, who's to say everything is still working just like new? Flog it off for the best possible price, spend a few thousand out of your pocket if need be and get another new car mate.
Edit: have you thought about getting your own repairer to assess the damage? if you can prove that there is more damage than the insurance company says (and have it in writing), maybe you can get the repair figure higher to get a write off. Get a few different quotes and pick the 2 highest ones.... the insurer does the exact opposite, gets a few quotes and picks the cheapest. Dispute the assessment that its 'only' $14k.
