Driving the Nismo
 I have owned my 2007 Frontier Nismo for a month now (purchased used). Fuel mileage is steady around 18mpg city. I have yet to take it on a trip along highways. It is a bit rougher ride than my neighbors 2006 Frontier XE due to the Nismo package. I would like to have his fuel economy but the towing capacity of mine will be handy with a boat and camper. The ride would be better with different tires. The electronic locking rear differential comes in handy when pulling a boat out of the water at the boat launch. Overall I would give this truck a well deserved A rating.
