Mercedes cars of this vintage were largely hand assembled, which also added to the variance. Regardless of the real numbers, the car was clearly unique in its day, and had no rival. It's possible to get even more performance out of these cars. There are simple bolt-ons available from experienced Mercedes shops that will get you up to 350 SAE net HP and improve the drive ability and acceleration times. It takes enormous amounts of horsepower to get the car over about 150 miles per hour because of the antique, boxy shape of the vehicle, so most current owners are making improvements for the sake of reliability and maintenance, not more horses.
