About 10 years ago, I remember briefly taking my 280SL to 120MPH....high revs near 6K, but car was very smooth, and she still kept pulling! I was quite surprised at the high end torque still available...wish I could drive a W113 on the autobahn for an extended time over 100...my W108 has only seen 80MPH, and my W123 was still pulling at 90MPH, which is amazing for a diesel!
