Here's yet another:

So that is 3 in two weeks of one model...it's hard to believe they only buyback a few hundred a year when three bluetecs show up in two weeks. They must sell 50X as many gassers as diesels so statistically there have to be many more gasser buybacks unless the buyback is specific to the diesel engine itself...either way I don't think it looks too good for the '08s.
