If you're searching for a 2020 GMC Terrain SLT for sale in Detroit, MI, your search ends here. Best of Michigan Auto Sales has this capable, stylish AWD SUV ready for a test drive — and at 65,906 miles, it's barely broken in for everything Detroit roads and Michigan winters can throw at it.
About This 2020 GMC Terrain SLT
The 2020 GMC Terrain SLT sits at the sweet spot of the Terrain lineup — above the base trims and loaded with the premium features most buyers actually want. This particular example carries 65,906 miles, which for a well-maintained Terrain is comfortably within the early stages of its long-term reliability window. GMC designed the Terrain to handle high mileage with ease, making this an excellent opportunity for buyers who want a nearly new feel without the nearly new price tag. The SLT trim adds luxury touches and tech upgrades that make every drive feel elevated, whether you're commuting through Midtown or loading up for a weekend trip up north.2020 GMC Terrain Performance and Engine
Under the hood of this Terrain SLT is a 1.5-liter turbocharged 4-cylinder engine — a powertrain GMC chose specifically for its balance of responsive performance and fuel efficiency. Paired with a 9-speed automatic transmission with overdrive (the 9T45 unit), this SUV delivers smooth, confident acceleration and relaxed highway cruising. The 9-speed gearbox keeps the engine in its optimal power band, which translates to better fuel economy on Michigan's mix of city stop-and-go and open freeway driving.
Critically, this Terrain is equipped with all-wheel drive — not an optional add-on, but a built-in confidence booster for navigating Detroit winters, slushy Wayne County side streets, and unpredictable spring thaws. AWD on the Terrain engages automatically when the system detects wheel slip, so you get the traction when you need it without thinking twice.GMC Terrain SLT Features and Interior
The SLT trim is where the Terrain starts to feel genuinely premium. Step inside and you'll find a well-appointed cabin with available leather-appointed seating, a responsive GMC Infotainment 3 system, and driver-assist technology that makes daily driving less stressful. The Terrain SLT typically includes heated front seats, a heated steering wheel, remote start, and a power driver's seat — features that Detroit-area buyers especially appreciate during the colder months.
Apple CarPlay and Android Auto compatibility come standard, keeping you connected without the distraction. The Terrain's interior is practical too — rear cargo space is generous for an SUV in this class, and the split-folding rear seats give you flexibility for hauling gear or passengers. Visibility is excellent, and the elevated seating position gives you the command-of-the-road feel that makes SUVs so popular in urban and suburban Michigan driving.GMC Terrain Reliability and Ownership
The second-generation GMC Terrain (2018 and newer) has earned a strong reputation for dependability. Owner reviews consistently highlight the Terrain's solid build quality, low maintenance costs in the early ownership years, and the long-term durability of its turbocharged 1.5-liter engine when properly maintained. J.D. Power and Consumer Reports have recognized the Terrain for above-average reliability in the compact SUV segment.
Common owner feedback points to a quiet cabin, a comfortable ride on rough roads, and the confidence that comes with GMC's reputation for truck-tough engineering even in their SUV lineup. At 65,906 miles, this Terrain is past the initial break-in period and well within the range where most buyers experience the fewest mechanical surprises. Regular oil changes, transmission fluid service, and tire rotations are the primary maintenance items to stay current on — and this SUV rewards that attention with years of dependable service.Why Buy From Best of Michigan Auto Sales in Detroit, MI
