I told „my“ dealership some time ago that l am 100 % pleased with their service department, but would not buy my next car from them (they p...ed me off with a 911 GTS l was interested in, which l discussed with them on a lesson learned basis thereafter). But, l think one can never be certain about a relationship, it is still a peoples‘ business - however, my dealer seems not to struggle very much selling many new cars. supply and demand seem to be in favour of the dealer.
