EDIT: I can't spell today, Ford can't see the forest for the trees, we'll call it even...
I will be a testimonial...
Had Ford offered a 4 door ranger, I would not be driving the GMC I have now.
I wanted something with more space, but don't care for the F150's much. I looked at the crew cab Colorado/Canyon's, but the only thing they beat the Ranger on is the size (the crew cab models are actually very roomy). Looked into Explorers and Sport Tracks, but I didn't want an SUV, I wanted a truck.
So there you go Ford, you had a sale, but lost it because you won't do the one thing that will take the Ranger back to the top
PS - Make a 4 door, and it will be my next purchase. Make a 4 door diesel, and I'll buy a gas for DD (lowered, of course), and Diesel for work (lifted, of course).
