Hi I have just purchased a used SLK, year 2009. It will be due a B service August 2015. An independent Mercedes specialist garage has quoted much more favourable costs for servicing compared to the local dealership. They say they use Mercedes qualified engineers, genuine M parts and update the Mercedes computer with all services carried out. Sounds good,but my concern is - if the work is not done by a mercedes approved dealer or franchise, will this devalue my car if i need to sell in the future?
I have been offered a service plan contract - cost for my car is £37 a month for 24 months which will give me 2 services - an A and a B service. does this represent good value as the independent garage has quoted significant savings for it claims the same services.
