The X-Men's Blackbird has always been my absolute favorite. A passenger jet with fighting capabilities and Shiar technology. It's about on par with the Avengers' Quinjet but the Blackbird was my first. The Blackbird was also made into a pretty cool looking toy by Toy Biz so that helps it get the edge. I still kind of wish I owned all the X-Men toys made when the show was on. The ads always sold me on them.
I also love the Fantasticar, whether it's the flying tub or the more fork-like design. The one from World's Greatest Heroes just felt like a regular jet, so I wasn't the biggest fan of that.
Hawkeye's skycycle is always awesome to see. There's also Scott's car from Evolution, which was a regular car, but a sweet looking ride.
Dishonorable mention has to go to Magneto's car from The New Fantastic Four. It's just the goofiest, most unnecessary thing ever. I got a kick out of seeing it show up in the Lego Marvel game.
