Crongrats to your boy on a terrific off-beat pick!
I liked these as well, they came out in my teenage years. 1 of 1,200? That's Mecum material right there!
Did it come with the TRX wheels, or just the steelies? This one has the "bubble back" upgrade that came from the LN7 - earlier EXP's had a flat rear window. The last ones had a more Escort-ish front end:
2-seaters, like the CRX. That limited sales.
