On the sporty side, the closest rides I still have are all motorcycles. One of my bikes while a good handler, doesn't compare because it is so much faster in a straight line. Another is a light cruiser style, similar in mid-range torque and certainly as nimble, but doesn't real feel that way, having a cruiser like turn-in..
From a fun factor, on back roads, my 1971 BSA comes the closest. Not the fastest thing out there, but extremely light compared to most modern motorcycles. There are obviously limits to comparing motorcycles to cars but the light handling, spirited exhaust note, the connected feel to the road, the simplicity, are all characteristics that connect the BSA and the Abarth with fun.
