Question Time
Basically in the mix of sorting out my next car and really want either the c63 or M5 and of around the 2009/2010 age, firstly its the c63 thats always had my attention but being a newb to euro vehicles id like to know whats some of the tips n tricks to servicing these cars in regards to dealers or doing it at say a performance workshop and why dealers may have the upper leg ?
Also would like to know about the car in relation to increasing power and when stock parts run out
Cheers
