Press the little silver button, and the aluminium bar angles out from its hiding place, a bit like a CD ejecting from its slot. Then pull on the end, and the door pops open. Jump in, and continue on your merry way in your merry little roadster. It was a unique entry system, ripped off by Aston Martin with the DB9 and all of its cars since.
The little Fiat was only slightly spoiled by the keyhole, which sat rather messily, three inches below the handle. But whatever. It still beats a cheap plastic flap.
