To take a Lotus Esprit, take it down to less than bare bones. Literally just the engine wheels flooring of the chassis. Then take apart a DeLorean DMC 12 and put the body (plus seats and such) onto it?

I dream of owning a DeLorean that isn't complete shit to drive.

The size of the cars seem similar enough to work with.
