Vacation in Florida in winter?

Hello all! As it looks like I’m going to be iced to Florida at the end of January at the beginning of February. Maybe someone from here has been there already in winter and can give me some tips and advice. I have planned my vacation so far that I land in Miami and then 14 days have time to drive around in Florida, bathe, shop and many many many car parts buy. Now I have a little thought because it is out of season and there are probably all a bit to renovate or that many cars are And where do I get, for example, oil filters, lowering spings etc……? does anyone know the typical pitstops? So I thank you in advance.. gruss Robi
