I've been truck shopping for the last few weeks and besides a used Denali I haven't seen anything that caught my eye. Well yesterday,I stumbled upon and 07 Suburban Z71 w/ 21K miles. The truck was BEAUTIFUL, fully loaded black on black with nav, back up cam, 2nd row captains chair and what really got me was the two tone interior. Now my question on the trim level hierarchy, where does the Z71 stand? Is that above or below the LTZ? If the truck was new which would cost more? I'm trying to negotiate a fair deal on the truck, but the dealer is really not budging. He's at 32K out the door and I want to be below that.
