Chances are also good that an Internet entity based in Mexico is not going to"buy" your timeshare, but is instead going to extract money from you while merely having you believe they are going to buy your timeshare. Stand by for the request for you to pay a "required" advance transfer fee, tortilla tax, escrow charge or some other such silly nonsense before you can "proceed". All that will ultimately "proceed" is money from your pockets to theirs. Save yourself the aggravation and just don't go there.
