I agree with Cody, it's a very hard car to put a value on....
If you could be happy with just a basic clean-up and drive as is, you might be all right, but you're paying TOP BUCK for a driver in my opinion.
It's not a Survivor.
What we have (or at least think we have) is an original paneled, numbers matching, low optioned, automatic, FC7 T/A in decent driver condition with an asking price of $50K and possible extra shipping costs etc...totalling $5K-$10K ?
I would think there are a few cars that fit that description around and available in the States/Canada for less money.
Personally, I couldn't live with it in it's current condition and would want to do a full ground up restoration. Unfortunately, the cost of resto would be almost as much money as any project car available at half the price.
When you're talking about stripping the body 100% for a repaint, rebuilding the drivetrain, installing new soft trim etc... it all cost the same. Only difference is that this car doesn't need metal work. Being an FLA car, I'm not even convinced of that without closer inspection.
I say take your wife to Australia for a well deserved vacation, but spend your car money Stateside.
