Great looking truck

So far after a week of driving the truck we like it very much. It is still too early to speak of reliability but so far all is good! Very comfortable interior.

Great so far!

I've only had the car for 10 days, but so far I'm very happy with it! Although it's in the small SUV category, it performs more like a mid-size SUV.

Best car we have ever owned !

Met all our reds and has a lot of new tech we didn’t know existed. The push button trans and camera system is awesome and helpful.
