Long before starting to badge 6.2 V8s as 6.3s as a ploy to sell more cars by referring back to its past, Mercedes-Benz created the best sedan in the world by jamming its largest engine into its smaller four-door's body. The 300 SEL 6.3 has been Jay Leno's favorite car ever since.
His 1972 6.3 cost $5,000 seven years ago and has 327,000 miles on it by now, yet everything is in working order, including the air-suspension and all the electronics. The thick leather seats and the wooden trim stayed in once piece as well over the last 43 years, which shows you what Mercedes-Benz quality meant back in the day.
Mercedes built many Autobahn missiles since this car, but this was the the only one that put Jay Leno in jail in the great state of Virginia.
Now, thanks to the conservative commenters on Youtube, this silver beast is going to be restored to its original glory instead of getting a new drivetrain from an SLS AMG.
