My father grew up a Ford guy, tried switching to GM for a few years and it didn't work out so then he went Dodge. He's still a Dodge guy today.
I'm open to other manufacturers, next car will likely be a VW TDI of some flavor. Love the fuel economy on those. Drove one, it was nice.
I drive a new Ford Escape at work and it's nice too, wouldn't mind having one myself.
However, in the diesel pickup truck world, it's really hard to beat that in line Cummings in the Dodge trucks. Those are just good engines. I don't know about the new Eco-diesels, the do put up good economy numbers. 28mpg in a 1.5 ton pickup? Wow... but are they reliable? No idea.
The real numbers are in resale value, just like our Kubota's. 10 year old Dodge Cummings keeps 60-70% of it's value at 200,000 miles. Same can't be said for Ford or Chevy diesels. However, that generally means you can get an equivalent used Ford or Chevy cheaper and still have a good working Diesel on your hands, so there is a drawback to higher resale value!
