The thread about Atkinson's F1 got me thinking - what other cars are so valuable they can't be written off? The Ferrari 250GTO and its siblings are the usual suspects, but newer exotics seem like they'd be more difficult thanks for carbon tubs and alumin(i)um space frames and the like. Taking a car back to the manufacturer is one of the most expensive routes to go - would it be worth rebuilding a similarly-damaged Veyron? Haven't some Enzos and Carrera GTs been written off already?
Mini Cooper S: + Strong performance, overall feel. - Over-long gearing.
Boxster S:+ Still an impeccable Sports car. - Very little.
