Mario that's such a shame.
When I read you were only thrird party insurance I thought Noooo what a plonka but your absolutely right, the coupe is now ten a penny and insurance will cost you more than the value of the car, especially when you add on the excess, plus the fact that they would write it off anyway if the chassis is twisted.
On the plus side, coupe's are ten a penny and you will find a nice replacement
Whilst you still have access to the car, take all the good bits of her and get ready to beautify the next one.
