The DRAG KING uses the newer version of a GT500. The GRIP KING uses the BMW M3 E92. The DRIFT KING uses a MAZDA RX-7. SORRY I don' t know the SPEED KING'S car yet. :( :(

You Have to go to the garage
I believe it's unlimited...I had over 175 cars in my garage
get 3 cars how easy was that!
beat the whole game
Type in "unlockallthings" in "Code Entry" and you will have everything

Not what I know of. The only way to customize my cars are in the career, which costs.
well what you have to do is complete at least 1 event on the day careera and every time you do one the more cars you win
When you have enough cash, go to the dealership (located in the menu that you look at your cars) and pick one you can afford and click buy it
type unlock all things and get out of your career load the game and you find 4 new cars
you can unlock all cars by entering the code: unlockallthings
