I bought a Quick Jack Model BL-7000SLX a few months ago. It is well made and performs as advertised; however, the length of the upper rail should be about 6" longer to accommodate MB vehicles. In order to get full bearing under the jack pads on our MB vehicles I purchased 2 pieces of 7" X 14.75 #/ft. channel 66" long. I place one piece of channel atop and centered on the SUV adapters positioned at their maximum spacing on each rail. Each piece of channel weighs 81 lbs. so it makes aligning the Quick Jack a bit more difficult.

Quick Jack advertises the maximum lifting point spread for the BL-7000SLX as 60" which would work fine for our MB vehicles if it was truly 60". The actual dimension is 55 3/8" using the SUV adapters. The first time I used the Quick Jack to lift our 1998 E320 without the pieces of channel, the SUV adapters tilted towards each other ... which made me feel very uncomfortable. I purchased the 2 pieces of channel before using the Quick Jack again. Buyer beware.
