For those not familiar with the Lotus Europa, I saw one a few weeks ago at a local Brit car show. Back in the 70's, rated as the best handling car in the world. And it was kind of a predecessor to the Boxster as a compact, lower priced mid-engine.
While it had a gun-slot rear window, the rearview mirror was hardly in front of you. More alongside your head, so not of great use!
