Casalini 550

The Casalini 550 is a compact city runabout that packs surprising practicality into a tiny footprint, making parking a breeze and daily errands almost enjoyable. It won't wow on long highway blasts, but for shopping trips and short commutes it's a clever, affordable alternative to a full-size car — proof that you don't need a giant wallet to get where you need to go.
