19: 1971 Porsche 911 T
The 1971 Porsche 911 T is perhaps one of the most underrated Porsche models. Leno purchased his 911 T from the original owner whom he tracked down after the car sat in a parking garage. Leno has put a decent amount of work into the car to keep it as close to its original condition as possible (via Motor Biscuit).
You won’t get any extreme modifications done to this Porsche, even the paint is still kept in the original shade of “Sepia Brown.” The 911 T was not the top of the Porsche lineup, but its performance was spirited, to say the least. In Leno’s entire collection, this 911 T is one of the most pristine originals.
