The two methods mentioned above are correct. There are two more that I can think of off the top of my head: servicing a car and looking at the Time Trial tier involving that car, before unlocking it. These options are useful for when you don't actually own the car yet, which is usually the case for new vehicles, as they are locked for a while.
