I think you should consider Pitbull's offer. After all CR does not take advertising, so how could they be wrong. Oh, and they have a lab, too. This fuel system problem was bad enough to trash the V6 ratings. After all, what do you expect. Now, if it was only a mechanical problem that did not involve fuel it would have been ok, like the wheels falling off of Durangos because of a failed ball-joint. Since it did not involve the fuel system it does not hurt the Durango ratings. Just because there were seven people killed or injured, with the Durango problem, at least they did not have a fuel leak.
If you think CR was wrong you should organize a letter campaign to annoy those folks. But they probably won't read your letters because they have made up their mind and are not often confused by outsiders. They have a lab and so they don't need any help, and they don't take advertising, either...did I say that, already, they don't, you know.
If you don't want to get skinned by a used car dealer you can save all that trouble and just buy one of their magazines. After all they don't take advertising.
