Unfortunately, you can not just buy a Supra and start allowing agents to use it as I'm sure others have already replied. You can however find an agent whom for a fee will show the property for you and enter it on the MLS for you as well. Which greatly increases your exposure, thus possibly adding to your bottom line. I hope this helped you.
