Best truck value on the market. I have this same truck with leather, moonroof and the Titan boxes, in pearl blue. Wanted the 6.5 ft bed so I went with the XD. It's replacing my '09 Frontier that has over 215K trouble free miles. Hoping for similar reliability with the Titan.
You can run it on either, you only need the premium to get up to 400HP and regular gets you about 390HP, that's the only difference but you can use either one of them.
