No greater love hath a man than he is selling his ML63 AMG to pay bloody school fees. Anyway, I'm loyal to ML range and will downgrade to a basic ML from about 2006-07 with hopefully under 100k. My problem is that I'm only looking at petrol versions and that means the Ml350 or ML500 from 2006+. As scarce as can be. The question I would value input on is whether a diesel ML can even be contemplated? My daily useage is 2-3 miles as most in Central London and all rush hour traffic. Every month (at most) I may do a 15-20 mile round trip on the Westway. And that's it. Not even a motorway blast for school holidays. All the advice seems to be that a diesel would be utter madness. Is that the general feeling? Are there any tricks or precautionary measures that could help? I know there won't be many occasions when I could clean the DPF with a hard drive so I need to be realistic. The second part of this question is that at the moment I get from 4-7mpg at best. Would a diesel ML be able to get 15-20mpg+ even with the short journeys? It's the difference currently from a full tank (90l) with a maximum range of 149 miles to anything better.
