If you wanted to do that, you would get your car without all the parts on it. Then buy the parts you want from any dealer or third party. Many of these items you can install yourself. Otherwise you can have them installed by a dealer (which would probably be pricey) or a shop. There are several vendors on here that sell the parts for good prices.
When you need to turn your car back in, uninstall the parts and return the car back to stock. Then sell your parts to other enthusiasts on the forums.
