One of the major concerns with MGs is their lack of dealerships for service. Many owners like (or at least are not opposed to) doing their own service. I am curious if any are using independent or non-MG dealers (e.g. BMW, Triumph, Honda) dealers for service? For example, I bring my car to a Goodyear service center (one I have dealt with for decades and really like) because it is more convenient and cheaper than the dealer. Is there anything similar to a Goodyear franchise type service center for motorcycles? Do you think (or know) if a typical BMW dealer would service a MG even if they didn't sell them? Also, I know that for cars using non-dealer maintenance services does not void a warranty, is the same true for MGs?
