Every time I see a picture with those 21" turbines I cry a little bit inside. With UK roads and UK climate I just couldn't bring myself to get them over the 19s, but they do look fantastic.
There are I think 3 RHD cars in the UK at the moment (they're touring around testing out charging points both in public and at prospective owners' homes). My VIN is up in the 40k+ range so no activity yet, but hopefully not too much longer.
