My 3.0is has just 38,000 on the clock, is in damned good nick and continues to be well looked after. Whilst i've got no plans sell her I got to wondering how important Main Dealer servicing is, if at all? Current history is nearly if not all main dealer (I don't have the service book to hand right now) or prestige marque independent. I am however fortunate enough to have a relative who owns a garage and has 50 years experience on everything from trucks to rally cars (worked with the Ford team for a while) has always owned something with a couple of litres under the bonnet and services all of our families cars. Cost wise i'll be paying the going rate but know I won't get ripped off, can have the book stamped, get an invoice etc., but will the saving be reflected in reduced values for being non main dealer? Should I even care?
