Please don't lump us Passat drivers in with Jetta drivers!
At least in my neck of the woods, many Jetta drivers are first timers or young kids. Though many are quite cool, nice people, you do occasionally run into those who are extra pleased to have bought a solid little car, and they start to get their heads filled with the idea that it is a mini-BMW - once that starts, they begin to judge anything else as lesser vehicles.
But Passat owners are often a more educated and financed crowd, and usually don't have anything to prove. We love our cars, yes, but also love other brands too. I check out other Passats, G35 Coupes, Corvettes, BMW M3s, Mercedes SLs, Mazda 6s, and a bunch of classic cars. Anyone who has done a nice job modding their car gets my respect too...even if it is not my favorite model.
I will race other cars...sometimes for fun, and sometimes because they goaded me on. I have even had Jetta owners challenge me to races! If I win, I give a thumbs up for the fun of the race, and if I lose I still had just as much fun, except sometimes I may roll down a window and ask what I just raced (what mods, what engine, etc)!
Anyway, good kill either way, and don't let it sour you towards the attitudes of ALL VW owners. I know a great bunch of very cool VW drivers down here, in all models, that would appreciate your car as much as another VW!
