The new Lincoln Continental?

You like Lincoln Continentals? We got 'em

The white convertible with the suicide doors had a hard top that got sucked into the trunk.

Bing, that started in 1977. It was the last year of the “full sized” Cutlass. They were selling like hotcakes, and the Olds engine plant literally could not make enough 350 engines, so GM started substituting Chevy 350s, hoping no one would really notice or complain. Well, they did, and they did. Several lawsuits were filed claiming “bait and switch.”

And thus was born GM’s “Corporate Engine Policy” where by buying the car, you agreed to accept engines from a different marque.

That same policy enabled NACAR teams to use Chevy engines in Cutlass fastback bodies (Which had fairly slippery shapes.) making Olds winners for a couple of years before the downsizing of the fleet changed everything.
