I think this very car has been discussed on
www.gt40s.com and from one of the owners it was discovered that is was a damn good copy. They are currently discussing what to do with it and some possible legal/retibution toward the previous owner. I'll have to see if I can find the number for you.
The chassis plate is frequently located in the engine compartment on the rear of the bulkhead. But, there are plenty of replica chassis plates too, so that doesn't go far to prove it is real or not. I have replica chassis plates myself that are indistingushable from real FAV plates.
