I'm a MA risdient with a MA drivers license. I go to FL frequently to visit my mother, and would like to buy a car in FL and garage it at her house. Can I get FL plates and registration with my MA drivers license? If not, what is a better solution?

I don't see a problem for FL, but every state differ, scroll down navigation to DMV and link to FL,,, If you want to provide your mom's Zip Code, I will let you know of any dealers that I might know with a good reputation.
