Am picking up my 2009 E350 CDI Coupe on Saturday (excited is an understatement). The dealer mentioned the fixed price servicing plan (i.e. 32 per month over 36 months covering 3 or 4 services). This sounds reasonable, but for example I think the car will need an ATF change in July when it is next serviced - would this be covered? Also does it cover brakes etc?
