FOUND: Arthur drives the hell out of Eames' Lotus Elise
Looking for the fic where Eames acquires a Lotus Elise and tries to impress Arthur by driving it hard and fast on curving wooded roads. Arthur makes him pull over and shows him how it's done - turns out he's a fantastic driver. I don't remember if they get together at the end. There was a similar story to this where Ariadne was in the back seat, but it wasn't a Lotus and it's not what I'm thinking of... Help?
