It's an LA Exotic. I'd start your research there. That photo is from 2011, when it was offered for sale in Canada. As for any "stories" that may be attributed to this car. They are indeed that - "stories". Anybody can create and tell a story. What value are you placing on your Coupe, and what value is the other party placing on the Cobra?
