are you just looking for original m3 parts or aftermarket m3 parts?
for original parts you are going to be looking at bmw breakers around your area or further afield and the occasional ebay listing. also it is worth getting a copy of either performance bmw mag or total bmw magazine which you can get from motorway stops or whsmith; as they have a lot of information on breakers and website you can find replacement parts on. however for oem m3 parts there are quite a few sites in the uk that cater for and i can give you a list of site to have a look at.
