My list:

Acura - Hondas for people with too much money
Audi - Volkswagens for people with too much money; or, Subarus for people that have the misguided belief that German cars are better than Japanese cars
BMW - Some cool M cars and then a bunch of overrated crap
Buick - boring cars for boring old people
Cadillac - Chevys for old people and black people with too much money
Chevrolet - redneck trucks, redneck cars, and the best American-made sports car
Chrysler - a German company trying to disguise themselves as an American company
Dodge - same as Chrysler, just a little more redneck
Ford - better than people realize, thanks to Mazda's influence
GMC - Chevys for people that can't spell Chevrolet
Honda - reliable and kinda fun
HUMMER - cars for people that want to piss off tree huggers
Hyundai - underrated cars
Infiniti - Nissans for people with too much money
Jeep - THE SUV (Wrangler) and then a lot of blah
Kia - LOL, whut?
Lexus - Toyotas for people with too much money
Lincoln - Fords for people with too much money
Mazda - cars for people that like to have fun when they drive
Mitsubishi - Lancer, Eclipse, and blah
Nissan - the Pontiac of Japanese cars
Porsche - proof that Germany should leave sports car making to Italy
Scion - Toyotas for young people
Subaru - WRX, STi, and blah
Toyota - reliable and very, very boring. If you drive a Toyota, you hate driving and just want to get there. (This does not include the Supra or Celica, the two decent cars that Toyota had and killed)
Volkswagen - the Apple of car companies (I mean that in the worst possible way)
Volvo - cars for soccer moms

My list:

Acura - Hondas for people with too much money :yes
Audi - Volkswagens for people with too much money; or, Subarus for people that have the misguided belief that German cars are better than Japanese cars
BMW - Some cool M cars and then a bunch of overrated crap :yes
Buick - boring cars for boring old people :yes Though I will say the new Lacrosse and the Enclave aren't terrible looking
Cadillac - Chevys for old people and black people with too much money Not entirely. My mom owns a CTS; they're pretty sporty and not really gangsta enough for the blacks. And Escalades are often-times used by rich soccer mom-types.
Chevrolet - redneck trucks, redneck cars, and the best American-made sports car :yes
Chrysler - a German company trying to disguise themselves as an American company :yes Not only that, but they probably have the most irrelevant cars ever...the 300, and that's about it.
Dodge - same as Chrysler, just a little more redneck :yes
Ford - better than people realize, thanks to Mazda's influence :yes Ford = GOAT. Especially out of the American companies.
GMC - Chevys for people that can't spell Chevrolet :no I would say GMC's are for people who don't want a Chevy, but can't afford a Cadillac.
Honda - reliable and kinda fun Reliable...but I'd say pretty boring.
HUMMER - cars for people that want to piss off tree huggers :yes :2thumbs
Hyundai - underrated cars :yes
Infiniti - Nissans for people with too much money :yes
Jeep - THE SUV (Wrangler) and then a lot of blah :yes
Kia - LOL, whut? Kia has actually made great strides, IMO. They used to be laughable, but now, they're seriously making some decent cars.
Lexus - Toyotas for people with too much money :yes
Lincoln - Fords for people with too much money :yes
Mazda - cars for people that like to have fun when they drive :yes
Mitsubishi - Lancer, Eclipse, and blah :yes
Nissan - the Pontiac of Japanese cars Nissan's are the poor man's Infiniti.
Porsche - proof that Germany should leave sports car making to Italy Awesome cars. Though I will say they're kinda overpriced, and you have to spend an ungodly sum of money to get the really good ones.
Scion - Toyotas for young people :yes
Subaru - WRX, STi, and blah :yes Those car/truck things are just :facepalm
Toyota - reliable and very, very boring. If you drive a Toyota, you hate driving and just want to get there. (This does not include the Supra or Celica, the two decent cars that Toyota had and killed) :yes And I'll add that their SUV's/Trucks can be very overpriced.
Volkswagen - the Apple of car companies (I mean that in the worst possible way) I can buy that.
Volvo - cars for soccer moms I would say Volvo is largely a family type of car, because they're supposed to be built like tanks.
