Seller's description
2015 GMC Sierra 2500HD SLT Crew Cab 4x4 Duramax Diesel Price: $29,900 Mileage: 172,000 miles VIN: 1GT12ZE8XFF112148 Title: Clean Ownership: One owner Accidents: None Selling my one-owner 2015 GMC Sierra 2500HD SLT Crew Cab. It has the 6.6L LML Duramax turbo diesel, Allison six-speed automatic transmission, four-wheel drive, and 3.73 rear axle. I have owned this truck since new and kept nearly every service record from the original purchase date. Most of the maintenance was completed by the GMC dealer or Diesel Doctors, and it has used full-synthetic engine oil since new. The truck is completely stock. It has never been deleted, tuned, or used off-road. It has a clean title, no accident history, and remains in excellent condition inside and out. Recent maintenance includes a replacement turbocharger assembly at 146,447 miles, A/C seals at 145,179 miles, serpentine belt and tensioner at 168,759 miles, and a new water pump and cooling-fan clutch at 169,699 miles. The SLT interior has leather upholstery, heated and ventilated front seats, a heated steering wheel, power-adjustable and heated towing mirrors with turn signals, and tilt-and-telescoping steering. The Duramax Plus Package adds an eight-inch touchscreen with factory navigation, Bose audio, and front and rear parking sensors. The Driver Alert Package includes forward-collision warning, lane-departure warning, and the Safety Alert driver’s seat. It also has center-console wireless phone charging and an engine block heater. Exterior equipment includes retractable assist steps, OEM GMC Denali wheels, and a Line-X spray-in bedliner. This is a documented, unmodified Duramax truck that has been cared for properly from day one. Full maintenance records are available for serious buyers.
