Thanks for your responses to my inquiry-was hoping for more though! I stand corrected on GMAC being owned by General Motors. They are a finance company. They used to be the finance co. for, and owned by, GM. They have since branched off from GM, and are currently owned by a company called Brookefield. They still finance auto loans as well as real estate and timeshares. Once the $650 (transferable lifetime) fee is paid, you can list your points/property for rent/sale as many times as you wish. They make their money off of the interest on the loans given to purchasers of the timeshares they sell (and the one-time fee, of course!). It is in their best interest to rent as well, as they are able to approach that huge experienced customer base for further sales. They claim to have many advertising venues, the most effective being showcase delivery in Orlando.
