Buying used Vespa

Hi everyone. I’m coming to Tulum as a tourist for a few months and looking to buy a Vespa. I did this back in 2022 but it looks like there’s a lot less available on Facebook Marketplace than there used to be. Since I cannot buy a new one and register it as a tourist, are there any other ways outside of FB Marketplace to buy a used one? Not really looking to rent.

PS if anyone here does have a Vespa for sale please let me know :)
