something you may be able to do because I think Florda also offers it is look for places that are essentially titled rent a wreck. Basically people rent out higher mileage cars that will run, just not always in the greatest of conditions(they're still roadworthy). They're incredibly common over in California(I use them whenever I go to visit family). You just have to be 18 years of age or older, have a driver's license, and have proof of insurance. Often you can get a week rental for 100 dollars.
