My 71 cuda clone was a gran coupe. Had the o/h console, leather interior, bulge hood, a/c, ps, pb, wood grain standard cluster, 318, auto/console with bucket seats, door/qtr belt moldings, qtr/deck lid trim. Was much more rare as a gran coupe.
I also have a 70 gran coupe, front elasto bumper, rear chrome, bulge hood, 318 auto/console, non a/c, rallye gauges, door/qtr belt mldgs. ps, pb, o/h console.
A couple of years ago I was at the nats and everytime a gran coupe drove by everybody went nuts. I guess they've finally gained acceptance.
