Legitimate Online Car Sweepstakes?

So I'm looking legitimate websites that have car sweepstakes, enter to win, that sort of thing. I know there are a lot of scams and spam websites so I wanted to ask here if anyone knew any websites that hosted ones that aren't fakes. Any help is loved, I don't live in an area that has a Mall close by to enter whatever contest they may be running so my only option is online.
