After 18 months and 21000 miles, I can honestly say I love this vehicle! Powerful engine, smooth ride, just dosent feel like a truck. I have driven my truck on several long trips and it cruises effortlessly at 80-85 mph, very quiet and comfortable. I've owned Toyotas, Hondas, Mazdas and a VW, and can say that so far, this is my favorite. I'm very impressed with the build quality of this truck too, especially the engine/transmission and fit and finish. I would definitely recommend that anyone looking at a mid-size truck to do yourself a favor and check out the Frontier!
Engine/transmisson, four wheel disc brakes, sunroof, utilitrack/bedliner, tow ability (I tow a boat with it), handles like a car, fun to drive!
Brakes sometimes squeak when backing up, paint chips very easily, that's about it.
