Did quite a search yesterday as I'm in the process of buying new wheels for the c270 - found blackcircles.co.uk was the cheapest site and has local fitting too. Other site worth a look is camskill.com. As a friend is the manager of ATS not too far away I'm planning to use the research to prod him on price!
The other interesting thing was opinions on this and the mbclub forum about different tyres for your vehicle - I found lots of info about different makes / types, including one that said exactly what I'm after for our relaxed long distance cruiser.
