Not that I know of.
You *could* have multiple dummy accounts, and be buying cars on those accounts and sending them to your "normal" account, and then deleting the saved data for those accounts to make it like you never bought those cars at all. That way, you could have each account SEND one car per day, but you'd have your normal account RECEIVE several cars per day.
But you'd need jumpdrives for each of your alternate accounts, and it would get to be a big ol' hassle, I'm sure.
This came to me earlier today, but I don't think I have the patience or organizational skills to pull it off.
