Sluggish Acceleration-1978 450sl

I have a 1978 450 SL with 72,500 miles which I owned for about a year and the acceleration from 0 to 10mph is very sluggish. The old owner had the same problem. After 15 mph it runs great. It starts up well whether it cold or hot. I replaced the fuel filter, sparks, and distributor, rotor, coil, air filter; replaced most of the vacuum hoses, coolant adjust the timing. Last weekend when I changed the oil, the car would not go up the car ramps. I had to give myself about five feet of running space to drive up the ramps. The car does not burn oil or smoke. This is my first posting.
