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.
