hi mate...i live in sandhurst berks and have always used knowle hill with my previous chryslers and jeeps, they phoned me saying mine was due a service soon and quoted me £240 for a 1 spanner service (which i think is just an oil and filter change walk round it and kick the tyres ) only done 4000 miles since last service although it was over 18 months ago, might look for a mercedes indie dealer, looking on the mb forums theres one in caversham called star motor sevices...post it up if you find anywhere else at reasonable cost....
