Update;
I missed out on the W code Boss but my guy in the States has now located two options.
1. Another Grabber Orange '70 Boss 302 auto, unmolested, matching numbers, no rust, in good driver condition.
2. A '70 Mach 1 M code auto in near show condition, very good colour, frame on restored 10 years ago and not driven much since. Very good eye candy.
If I were to onsell those cars here on OZ what sort of money do you think I could ask for either of them in an "as landed" condition?
