Elan S1. Although, I have a preference for the Lotus Cortina alas not found here in the game.
A fully modded Elan is an amazingly quick and agile car. Secondarily my 111r RM, but my Evora is only about half a second slower than the RM on most tracks, so it's certainly a brilliant car.
Pretty much any Esprit. They are incredibly fast more than able to compete with most of the "supercars" that cost a lot more. Any of the Lotus cars are good though.👍👍
