I recently acquired a 87 560 sl with in great condition with only 37,000 miles on it. (My bosses car). The car had checked out fine by a MB mechanic and I've had all of the fluids changed. My question is that this idles at about 550- 600 rpm and tach registers 500 rpm when foot on the brake at a light.
Starts up great, seems to idle smoothly, no hesitation, bucking or stalling problems. Since all of the american cars I've owned in the past ( mostly older vettes) idled at 750, I was wondering if the numbers my mercedes is showing are normal or should I have the car looked at as a precaution. I am planning my first major road trip next weekent ( about 5 hours to cape may NJ) and don't want any unexpected problems.
Any input would be greatly appreciated. Thanks

Steve,

Your car idles as it should, in "D" and at operating temp should be 500-600 RPM.
