overall
Summary
With 3,875 currently listed for sale and an average price of $26,188.00, 31.5% of 2018 GMC Sierras for sale on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2018 GMC Sierra 1500 4.44 / 5 stars and CarGurus experts gave it an 8.17 / 10.
71.3% of 2018 Sierra 1500 models on CarGurus are accident free.
Why it stands out
The 2018 GMC Sierra 1500 stands out as a full-size pickup that was kept relevant with more standard content and safety features just before a redesign. GMC also made the reversing camera and the previously optional infotainment system standard equipment, which gives this truck a stronger value story than its age might suggest.
That added equipment helps the Sierra 1500 appeal to buyers who want a truck that feels more modern and easier to live with. Owner feedback also points to a smooth ride, a luxurious feel, and a comfortable interior, along with praise for its power and fuel efficiency. At the same time, some owners mentioned missing features such as backseat vents and basic safety options, and a few raised concerns about engine performance and transmission issues.

Only thing i didn’t like is the gas mileage. Mine is slightly lifted though and averages about 13 miles to the gallon

2018 GMC Sierra. Simply the best driving & riding truck I have ever owned. The magnetic ride sets it apart and was the reason I purchased a 2018 vs the newer body style without it. It’s also the reason I choose it over similar Ford and Dodge trucks.
