Should I buy a 2015 GMC Sierra 2500HD or consider a different year?

Choose the 2015 if:

• 25% of listings are priced as good or great deals.
• Price trend: Prices have softened 4.04% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.

The bottom line: If you want the strongest mix of owner satisfaction, current pricing, and available inventory, the 2015 is a sensible primary choice.
