I drove the Frontier and the Tacoma - the frontier was my favorite by far (although some of that had to do with the sales guy). The v6 has power to spare, the seats are comfortable, and I'm getting 19 mpg mixed driving, which is about what my old Volvo 740GL was getting. Couldn't be happier with this truck.
Power, ride, looks, power.
has some annoying squeeks that come and go - right now it's a slight squeak from the sunroof cover if it is closed all the way.
