2018 Nissan Frontier Crew Cab S 4dr Crew Cab 5.0 ft. SB (4.0L 6cyl 5A)
Great all around truck
 I have the 2016 Frontier crew cab S model, 4 liter automatic,  the shift is very smooth, great acceleration.  I do mostly city driving, I get any where from 15 to 17.5 mpg in the city and 22 to 24 on the highway. It all depends on how you drive it.  The rear seat leg room is a little small, but the truck will fit in my garage.  Easy for me to get in and out of. Cock pit area is nice.  A/C, blue tooth, entertainment are all very good.  Some of the articles you read about gas mileage compared to Toyota Tacoma are misleading, there are no real noticeable different between the two, maybe 1 or 2 mpg. It's all about how you drive it. Plus the Frontier is somewhat lower in price.  No big deal that the overall styling is pretty much the same for the last 10 years or so, it's reliability that counts. The handling on the high way  holds the road very well, the ride is a little stiff going over bumps, but it's a truck.  I added my own rear view camera and monitor for around $55.00 from Amazon.
