At least three cars from manufacturers of European base.
At least three cars from manufacturers of Asian base.
At least three cars from manufacturers of North American base.
Manufacturers such as Lexus, Infinity, Scion, and Acura I credit to their parent corporation, so they’re Asian. This does not say manufacturer partnerships can be counted. [Purchasing, partnering] and [parenting, spinning-off] are different animals.

Each car is raced once and is then disposed. You are allowed to select different years / trims of the same car. Meaning you could select a 2005 Acura NSX, a 2005 Honda NSX-R, and a 2005 Honda NSX-R GT as three of your choices. What you may not do is build one car to fit different classes.
 
Multiple people may race the same car. In fact, if one person has raced an S class car at a track and they like the result of someone else's car, they may ask to use that car at a future race. In this case the car would not be disposed.
