combinations

Hi all, I've had my c63 estate for a couple of years now. It is cavansite blue with a porcelain interior. When I bought it from the main dealer they told me that it was the only estate in this colour combination registered through Mercedes in the country. I was wondering how true that was...

I would like opinions regarding the best wheel and tyre size combinations for my SLK 200K. Same all round? Bigger back, smaller front? Thanks.
