Give it up already......the prospect of a new model Avalanche that is an Avalanche and not some tarted up Colorado with an Avalanche nameplate is as dead as the El Camino.
My '13Z71 Avalanche with leather, Nav, sunroof, rear entertainment, trailer cooling and brakes packs, 2 spd Xfer case etc, etc at $50K stickered for about $5000 less than an equivalent equipped Tahoe and $12K less than Suburban. Now the equivalent Tahoe is close to $70K and Suburban $75K+, or you can get an Escalade for $100K. So even if GM came out with a '16 Avalanche you'd be looking at around $65K+ for an equipped new one......and I, and likely a lot more of you, won't spend over $60K for a new one even if it was offered, and if no new ones, no more late model low mileage used ones either.
Beat the crap out of my '12 with all the construction and landscaping projects and kept the '13 cherry....not a scratch on it and engine purrs....for a Sunday driver. Just did my 4th oil change at 9,000 miles and at this rate it will outlast me. That Fairway Green paint, anniversary emblem and two tone Z71 4x4 badging on the rear quarter along with chrome handles, and chrome folding/directional mirrors and chrome tow hooks (swapped from the '12) always draws looks. Even had an offer for the $40K I paid for it.....no deal couldn't replace it.
