2006 Nissan Frontier King Cab XE 4dr King Cab SB (2.5L 4cyl 5A)
Excellent truck at a great price
 I was torn between a Toyota Tacoma and the Frontier, and with the Frontier I got the same features for about $1000 less. Having owned  a Frontier in the early 90's, I'm happy to say the ride of the new Frontier is much smoother, very car-like, as opposed to the older truck whose ride was very stiff.  Sit inside the XE and you will be surprised it is the lowest trim level. You ride high up like an SUV, and both interior and exterior are stylish. Only negative I'd mention is that the 4-cylinder engine has a whiny sound. However, it's got excellent acceleration, I was very surprised.
