Lets say I want both the silver and the gold prize car. Can I get silvers on the test win the first car, then go back and win gold and the the other prize car?
If you got gold, you should get all three (total). You get one car for each. If you get a silver first try, you'll get two cars. If you get gold first try, you'll get all three. If you get a bronze, you'll get one, then if you try again and get a silver, you'll get one MORE (total of two), etc.
