One word: awesome. I absolutely love the Alpina Roadster S. It looks so much better than the M. Especially with the white light conversion in this silver colour. I've read quite a few reviews of the two cars, and for me it'd be the RS every time. I'm slightly biased as I've already got a B10, and it would be the perfect partner. I'm sure one will be gracing my driveway in the not too distant future
