No, it is possible rent cars too. As long as you have the car unlocked in the career series, you could go to that series, buy it, upgrade it, then go to the WTT and run it.

Then cloud restore, it will put the car back as "unpurchased" and return all your GC.

If you do this, I hope you get caught... :)
