I'd echo that Jay: thought I wouldn't get on with my Moto-Lita 14" walnut wheel - but somehow it just feels right. Maybe it echoes the vintage feel of the car.
I also have a Volvo XC60 - auto box, high riding, fat leather wheel - so the contrast could hardly be greater. Yet somehow both cars just feel "right" for the job they do. I wouldn't swap the Roadster wheel for anything chunky and black, any more than I'd put a woodrim on the Volvo!
