Im not sure how many new Mercedes CDI ML and GL SUV diesels are out on the road, but Ive not seen too many around Ohio? (took this photo today while traveling in Akron Ohio -- larger image)

I like the slightly larger size, but suspect the price is going to take it into the VW Touareg V-10 diesel land? I might just have to tool down to my local MB dealer and take a test drive ... just to see if the new body style and CDI engine are a good match for the smaller ML and the larger GL. I did test drive the R wagon gasser when if first came out and thought it drove smaller than it really is ... its a big vehicle!

I know its important that all the new models focus on the ULSD, but havent heard much about them running on biodiesel?
