Hi;
Since I have seen some mention on car dealer sticker/plates on vehicles, I have noticed that if you see a dealer sticker from a so-called upscale dealership, the drivers tend to be more aggressive and/or road hog-ish. I guess people think that if they go to a dealership for self important people, they have the right to have right of way demands.
Since I drive for a living, I see no reason why a car from an upscale dealer will not go crunch any differently from that of lesser known dealership. So why the snobishness ?
