1999 Mercedes-Benz SL73 AMG

The mighty Mercedes-Benz SL73 AMG: A car that can’t be mentioned without saying the word ”Zonda” in the same sentence. Less than 100 of these monsters started life as a regular SL600 with the M120 6.0 liter V12 and were shipped up to the AMG factory for some special touches and an increased displacement to 7.3 liters good for over 540 horsepower. The eponymous 7.3 liters were so good that they made their way in the Pagani Zonda and the rest was history. With so few of these cars made, if they ever come up for sale, they usually don’t go for cheap nor stay for sale long. Now that this 1999 is available for sale in California, it’s time to take a close look at this thing while we can.

1999 Mercedes-Benz SL73 AMG

The breadth of engines offered in the R129 Mercedes-Benz SL is rather remarkable. US customers were limited to the 3.0 (and later 3.2 liter) inline-6, 5.0 liter V8 and 6.0 liter V12. It’s not surprising that other markets had access to other, more special variants. One of the largest displacement engines offered in a Mercedes-Benz in the post-war era found it’s way under the hood of the car we see here, the SL73 AMG. And yes, the number 73 denotes a 7.3 liter V12 resting under the bonnet, capable of 525 horsepower and 558 lb. ft. of torque. This engine would go on to power the dramatic Pagani Zonda S, a supercar capable of almost 200 mph.
