[HOT NEW]Alfa Romeo 4C Spider Review Following through on its Geneva concept and year-end rumors, Alfa Romeo has introduced a roofless version of its mid-engine 4C at the 2015 Detroit Auto Show. br br Like the Lotus Elise, the canvas top on the 4C Spider isn't some fancy automatic roof. Instead, owners will need to manually sort things out. Unlike the Elise, at least, the 4C's top is easier to manage when both fixing and removing from the mid-engined sports car's body. For those that prefer the security provided by a hard top, a removable carbon-fiber roof will be added after launch. Aside from that change, most of the tweaks for the 4C Spider have to do with options and equipment.
