The verdict
The 2025 GMC Sierra 2500HD SLT Crew Cab 4WD is listed at $55,995 with 60,739 miles. The Caboose score is 7.8 out of 10, built from three things: how far below market the price sits, how much of the 200,000-mile target is still ahead of the odometer, and how often this model reaches 250,000 miles in the iSeeCars study (17.2% of GMC Sierra 2500HDs do).
The asking price is $2,172 (3.7%) under the CarGurus expected price of $58,167, which is a real discount rather than a rounding gap. That puts it in the middle of the pack, so treat it as a candidate to compare rather than a car to rush.
