Hi all I'm new here and to Mercedes in general. I'm one of those strange people who like the CLA so bought a 220 AMG sport (ex demo model!). The Merc dealership have offered me a service plan but am wondering if this is good value or better to take it along to a local garage. Problem is I'm new to the area I currently live so have no idea which are the good garages. I'm tempted to go for the plan as its easier...thoughts anyone? Apologies if this isn't the right place to ask! TIA A.
