The Buick Reatta was a hand-made luxurious sports coupe produced at the Reatta Craft Centre in Lansing, Michigan and sold by the Buick division of General Motors from early 1988 to 1991. Like the Cadillac Allante, it was based on a shortened version of the GM E platform used by the Cadillac Eldorado, Oldsmobile Toronado and particularly the Buick Riviera, with which it shared its advanced electronics and interior furnishings.
