I'm thinking of buying a Frontier...

[Bailey Guns]

I didn't say it'll set the US market on fire. And yes, diesels (in smaller vehicles) haven't been big sellers in the US historically but they have been overseas for years because they're dependable and efficient. That's becoming more and more apparent to US consumers...especially the efficiency thing.

I guess I should've qualified my statement about the Colorado...by "big seller" I meant I think they'll easily sell all they produce.

I also disagree with your assessment of GM truck quality though I can only speak to the full-size trucks. I don't drive small trucks because they can't do what I need them to do and I like the room offered by a full-size truck. But I'd put the quality of my 2012 Silverado 2500HD (gas) up against anything.

ETA: I'm outta this discussion because I have nothing to offer in answer to the OP's question.
