Jay Leno's personal car collection features all sorts of neat, unrestored old vehicles. This is one of the coolest that he has. It's a 100-year old Pierce Arrow Model 66 that's never been restored, and still runs perfectly, right down to the gauge cluster.
This particular Model 66 was the last example to roll off the production line in 1918, and features a 14-liter inline-six cylinder engine with a redline of around 1800 rpm. Despite its impressive age, the drivetrain and chassis are still in impeccable condition, which, according to Leno, is thanks to the defunct American company's fantastic build quality (though we think his team of on-staff mechanics might also have something to do with it).
Thanks to the gobs of torque provided by that massive engine, merging with modern-day traffic is no problem, as Leno and Patrick Craig of the Pierce Arrow Museum demonstrate in this latest episode of . Watch for yourself.
