I have no specific measurements as you do, Lenny, but I do, or did, have three other vehicles to compare our '00 ML320 to - a '99 Camry (sold this past winter), an '03 Camry and a '78 300SD. We bought the 320 new, as with the two Camry's, and have known the 300SD since new and owned it since 1985. Since new we have thought the ML's air conditioning was weak, as we also felt about our first ML, a '98 320. The air vent temperature was noticably higher than our other vehicles and we have to run the ML fan at a higher speed for the A/C to keep up. Even the '78 A/C, which had been recharged once in the late '80's, is more adept. The issue with the A/C is not all that unlike the issue with the driver side footwell being so cold in the winter. Maybe it is an air distribution problem.

As a side note, the climate control in the 300SD is the best heater and A/C system we have had compared to our many other vehicles we've owned. When we set the dial at 72 degrees the interior stays within a small comfort range whether heating or cooling - very nice.

We are currently using the 320 on a long trip with tempertures in the 90's, moderate humidity, and the A/C is doing ok. However I feel this is one of the areas that could have been improved on in this vehicle.
