Back in the 1960s, a mate had a DS19 in Australia. I totally agree with Jay Leno's assessment. It is a simply amazing vehicle, and as he said, supremely comfortable. The suspension was like riding a cloud. I still recall the feeling of my shoes sinking into the soft floor in the back seat.
Sluggish to accelerate, but once up to speed, one could pretty much ignore corners and should one have to stop, the massive inboard disk brakes with their vented cooling just ripped the speed down to zero in a moment.
