In March of this year, I purchased a new Mazda 6 TS2 Estate from a main dealer and it is now coming up for its first service (12,500 miles). It was suggested to me at the time that if the car was not serviced by a Mazda main dealer, then the warranty would be void. Is this correct? My understanding of this is that this restriction cannot be implemented by law as this limits the choice as to where you can have serving done. I buy my cars new or nearly new and have always used a very good local independent garage that provides me with a very good personal service. We had a Mazda MX-5 a couple of years back which had one service done by this local garage before being traded in for a BMW Z4. We had some trouble with this as the main Mazda dealer claimed they could not find any service history, although the local garage claim to have entered it on the main Mazda computer service programme (I produced an invoice for the BMW dealer to prove the work had been done). It could be that the law has been changed and that a main dealer can insist on a vehicle being serviced by them to validate the guarantee. Your comments on this would be greatly appreciated.
