This video was talked about in the W126 forum over at BenzWorld. As pointed out, its a SE not SEL. The video was definately filmed in Europe, precisely England (RHD and English speaking). No diesel W126 were offered in Europe either. The comment on how a diesel wouldn't go up high because its heavier doesn't make sense. It would have crashed and reacted in the same manner. Diesel W126's are also capable of going 100+ mph. May not get their as fast as a 560, but it certainly will get up their.

The SE did not have a driver which would add say 180-200 pounds (average male weight) and figure in the weight difference between a SE and SEL chassis on top of that.
