What am I looking at?

Way too much $$$, am curious though if it could be a Mexican model. I recently saw a 70 or 71 A body, with some interesting differences, including IIRC Super B badges, twin hood scoops with 290HP badges, a 318 4 spd o/d trans. Car was fully documented, I spoke with the owner at length, he has verified the origin as Mexican built. Interesting car.
