Wow...driven as opposed to owning? I've driven hundreds of cars including nearly every sports car and muscle car while working at auto dealers in the '70s/'80s/'90s. Any car that really feels good in your hands is a smile-generator, IMO. I remember the first time I drove a euro 930 in the '80s alone, when I floored it in 1st gear and the boost spooled-up it was like being on the most amazing roller coaster as a kid and being tickled at the same time. Massive smile. Maybe laughing.
The Sunbeam Tiger with its crazy torque/weight ratio in a small sports car is similar. Laugh out loud when it breaks traction from a rolling start @ 20-30 mph. There are under-powered cars that also can be a blast to drive on the right road.
My Dad's V-12 4-speed E-type convertible was always good for a smile or two on the rare occasions that I drove it alone w/ the top down on a summer day as a 17 y.o.
