I was wondering the same thing. Here is a list of his designs I found on the internet;
Alfa Romeo Montreal
Alfa Romeo 33 Carabo
De Tomaso Pantera SI
Ferrari Dino 308GT4
Most of the FGT experts will travel to do your PPI.
Funny, being a car nut for 40+ years, I only became aware of Montreal's a few years back. Love the design, so many Miura styling ques. I too like your collection.
I think a lot of states credit trade-in value against the new purchase sales tax.
That $25-$30,000 tax credit may go a long way in helping make a dealer purchase palatable.
For the right car and the right pricing of course.
