2006 Gmc Sierra 2500HD Extended Cab 4x4 SLE Duramax Diesel LBZ

Seller's description

2006 GMC Sierra 2500HD SLE 4x4 Duramax LBZ for Sale Clean and well-maintained 2006 GMC Sierra 2500HD Extended Cab SLE 4x4 with the sought-after 6.6L Duramax LBZ diesel engine and Allison 6-speed automatic transmission. This is a rust-free, accident-free private-party truck with a clean New Mexico title in hand. The truck has 225,000 miles and has been owned in California, Oregon, and New Mexico. It is currently located in Tijeras, NM. Asking price is $18,500 firm. This Sierra is stock mechanically and cosmetically, with no performance modifications. It has been properly maintained, with recent fluids and filters completed. Maintenance records are available, including a spreadsheet from the previous owners and a Carfax from May 2024. Features include a 6.5-foot bed with spray-in Line-X bed liner, Westin bed mat, matching topper with roof rack, Westin running boards, Hayes trailer brake controller, front 2-inch receiver with trailer wiring, Rough Country rear under-seat storage, Bluetooth added to the factory head unit, and a new windshield. The exterior is in very good condition with clean paint and body, no rust, and no major dents or scratches. The only noted cosmetic issue is light clear coat fade on the roof. The interior is clean, with no ripped seats or major wear. A/C blows cold, heat works well, and the power windows, locks, mirrors, and 4x4 system all function properly. This is a strong-running LBZ Duramax truck that is ready for towing, work, or daily driving. Serious buyers only. Cash or bank cashier’s check accepted. Proof of funds or cash in hand required before any test drive. Trades considered only for a clean-title 2015-2017 Ford F-150 5.0 V8 4x4 or 2014+ Toyota Tundra 5.7 V8 4x4 of equal or lesser value.
