Is it just me, or is this conversation turning into one of those things the original poster DIDN'T want it to turn in to? I don't race, I don't have a high performance car. I'm totally neutral, I love cars. Full stop.
I can appreciate a well modded car, of any type(I live in Denmark, so they're all imports

). I think its important, when you see a modded car, to try and think why the person did it?
Does he want looks and loud music for cruising/winnig shows(

Does he want to smoke everything out of intersections(

Does he want big block rumble/torque/nostalgia/power/straightline speed(

Does he want to go up into the mountains/backroads on the weekends and tear up some twisties(

There are a million other reasons to tune/mod your car, these are but a few.
Now, I can relate to the urge one feels, to throttle the punk in the civic with the huge rims and what looks like a drainpipe bolted to his exhaust. But honeslt, I experience the same thing when some jackass in a poorly maintained V8 rumbles by at night, rattling my windows...
So, people who love their cars and aren't willfully abnoxious toward the rest of the world, I like, regardless their choice of brand.
People who don't take proper care of their car, and are willfully obnoxious, I hate, also regardless of their choice in brand.
I lost track of where I was going, but there it is. my $0.2
