I traded my bought new 06 Crew in for a 16 Colorado Z71 Ext Cab.
I find there are days when I miss my Frontier, and there are days I'm happy with the Z71. Getting used to the 6 speed shifting is tough- it does not like to downshift. You have the 8 speed though?
The Wrangler Authority Kevlars were on my list of "get rid of"! I found they always rode hard and got progressively harder and squirrelly to the point at 25K they were so hard- I was bouncing and shaking on some expansion joints.
I love the mileage of the Colorado- I got at least a 4 MPG increase.
My son just moved home- and brought with him a 2013 Pro-4x in bright blue. When I feel the need for some Frontier love- I can drive it.
I find that the more I drive the Colorado- the more I want the closer, tighter cabin and layout of the Frontier. After a bit more than a year- I am still mixed up in orientation of wipers and other controls.
I was a bit hard pressed to ditch my Frontier at the time- the Core Support and much of the hardware and associated connecting pieces were swiss cheese. My front end was making horrible noises. I was told at least $2K to repair just that, and I know it needed a lot of other work as well- but it was mine and paid for. Long Bed Crews were real tough to find, and actually all I could find here then were SV Crews- without the VTP. My front end noise stopped for a couple of days- I had it appraised and bought the Colorado.
