I don't understand why the extended cab wouldn't be more popular, for me it was a perfect compromise (is that an oxymoron?) - extra seat/cab space, full 8 foot bed in a relatively manageable size package (compared to a crew cab/long bed). The rear seat isn't cavernous, but it is usable. I rode back there from Missouri to New Jersey and back and was completely comfortable (granted, I'm only 5'-8", but still...).
Couldn't agree with you more about the Tacoma. What IS is with these car company designers? They got the damn design RIGHT the first time, then, over time, they seem to think they need to "update" it. Did the same thing with the Yaris - started out perfect, they they kept screwing with it until it was so ugly, they couldn't sell any of them.
I my opinion, Ford did the same thing with the Mustang - they got the original "retro" design right then kept messing with it. Interior too....
That statement will probably start a fight, but that's what I think.
