7. 289 AC Cobra
Leno has a bunch of unique sports cars in his extensive collection. The AC Cobra is a well-known roadster that was designed by Carroll Shelby, and this is what made the roadster a unique addition to his collection. But when it comes down to getting the AC Cobra on the road, the 289 is one of the most fun-to-drive engines. However, the 289 AC Cobra is also one of the most impractical cars for several reasons. The two-seat roadster is very uncomfortable, and although the speed is great, the rest of the car just doesn’t add up.
The roadster didn’t come in a hard top configuration and that was part of the essence that made the AC Cobra something unique. Leno would be hard-pressed to find another roadster as performance-minded as this one. But he has such a strong collection of unique sports cars that he could let it go.
