About This 2020 GMC Terrain SLT
This 2020 GMC Terrain SLT Sport Utility is a four-door SUV with 97,782 miles on the odometer — a number that tells you this vehicle has been driven, but by no means worn out. The Terrain is widely regarded as one of the more durable compact SUVs in its class, and at this mileage, there's still plenty of life left in it. The SLT trim puts this particular Terrain above the base and SLE models, meaning you get a noticeably more refined experience inside and out. Stock number 10518 is available now at Best of Michigan Auto Sales in Detroit — come see it in person and you'll understand why these crossovers hold their appeal so well over time.2020 GMC Terrain Performance and Engine
Under the hood sits a 2.0-liter turbocharged four-cylinder engine paired with a 9-speed automatic transmission with overdrive — GMC's 9T50 unit. This combination delivers a strong balance of performance and fuel efficiency that's well-suited to Detroit's mix of highway commutes and city driving. The turbocharged engine produces responsive acceleration off the line without sacrificing fuel economy, which matters when you're navigating I-94, the Lodge, or the Southfield Freeway on a daily basis. The 9-speed transmission keeps the engine in its optimal power band, making highway cruising smooth and relaxed. Front-wheel drive keeps things simple, predictable, and cost-effective to maintain — a smart choice for buyers who want reliability without the complexity of an all-wheel drive system.GMC Terrain SLT Features and Interior
The SLT trim is where the Terrain really starts to feel premium. Expect features like leather-appointed seating, heated front seats, a power driver's seat, and GMC's IntelliLink infotainment system with a touchscreen display. You also get Apple CarPlay and Android Auto compatibility, a built-in Wi-Fi hotspot, Bose premium audio, rear vision camera, and keyless open and start. The interior is thoughtfully laid out with quality materials that hold up well over time — drivers moving up from a base trim will notice the difference immediately. Cargo space in the Terrain is competitive for the class, with a flexible rear cargo area that makes grocery runs, weekend trips, and everything in between manageable without compromise.GMC Terrain Reliability and Ownership
The 2020 GMC Terrain benefits from a significant redesign that occurred in 2018, which resolved many of the mechanical concerns that plagued earlier generations. Owners of this generation consistently praise its build quality, comfortable ride, and the refinement of the cabin. The 2.0T engine is a proven unit shared across the GM family of vehicles, with a solid track record when properly maintained. Routine maintenance — oil changes, transmission fluid, and brake service — is straightforward and affordable. At just under 98,000 miles, this Terrain is entering a phase where attentive ownership and regular maintenance will keep it running strong well into the 150,000-mile range and beyond. It's a smart, value-conscious choice for buyers who want a near-luxury feel without a luxury price tag.Why Buy From Best of Michigan Auto Sales in Detroit, MI
