The 1988 Reatta, probably the least promoted new model ever released, Buick put all its' eggs in the Regal promotion bag when it was instead being introduced to Dealers. The Reatta was there as a Showroom attraction only. The first production car accepted for delivery to dealers, the first of just over 21,000 total coupes and (limited) convertibles.

Pity Caddilac Div. had control of concept and engineering resources in those days, stuck with 160 hp and no tranny options, well
I fixed that! This should say it all!
