2007 Nissan Frontier King Cab XE 4dr King Cab 6.1 ft. SB (2.5L 4cyl 5M)
Four's fine
 Was set on a Tacoma. Looked at the Frontier in the 11th hour. The stock and option values were better. The 6 is a great value for lots of extra power, but I wont be doing any heavy hauling. Also nice to have that extra power on tap but as the price of gas goes up-my need for speed goes down. The 2.5 isnt exactly a small 4 anyway. I took mine through the gears @3000 rpm and found the power more than adequate. It's too new to check the gas mileage but I'm sure it will be decent after switching to full synthetic Mobil 1. There are some minor negatives, but overall this is a great truck. Perfect size. Nicest looking.
