I just found www.mkb-tuning.de on www.driftworks.com from another W202 owner, some of the stuff they have for even a C180 looks pretty good, cams n stuff to go to 141 bhp, stroker to 2.5L from a 1.8 etc... and it al seems realy good. Thing is has anyone actually used them? Id like to know what the prices, service and quality is like coz that website is making me seriously think about tuning up my C180, asked for a quote on the basic M111 1.8l kit they have, but as its sunday Im not likely to get a reply soon.
