Moving with the old buddy

Oh Santa Maria Vergine, help us to survive this absolutely unexpected moving! My great-granddad Luca borrowed us his 55 years old Fiat 500. He still loves to ride in it with great-grandma Francesca during their dates, but I've never drove his car! I have no idea how to shove all this endless boxes into this teeny-tiny car - it has no trunk, no roof racks, no hook for trailer, olny folding roof to catch more wind! Ooh! Mamma Mia! Non mollare!
