Best of Michigan Auto Sales has this capable, well-equipped AWD Sport Utility ready for its next owner — and at 81,509 miles, it still has plenty of road ahead of it. Whether you're navigating the streets of Detroit or heading out on a longer haul, this Terrain SLE checks the boxes for everyday practicality, modern technology, and genuine reliability.

About This 2020 GMC Terrain SLE

The 2020 GMC Terrain is one of the more underrated compact SUVs in its class, and this SLE trim hits a sweet spot between value and features. With 81,509 miles on the odometer, this Terrain sits well within a range where buyers can expect years of dependable service — especially with proper maintenance history. The SLE is GMC's entry-level trim on the Terrain, but don't let that fool you. It comes generously loaded with features that many buyers associate with higher-priced competitors. This is an AWD model, making it a particularly smart choice for Metro Detroit winters where road conditions can change fast.

2020 GMC Terrain Performance and Engine

Under the hood, this Terrain runs a 1.5-liter turbocharged 4-cylinder engine paired with a smooth-shifting 9-speed automatic transmission with overdrive (GM's 9T45 unit). This combination delivers a balance of responsive power and genuine fuel efficiency — a strong selling point for Detroit commuters dealing with stop-and-go traffic on I-75, I-94, or the Lodge. The turbocharger gives the engine a punchier feel than a naturally aspirated 4-cylinder of the same displacement, making highway merges and passing maneuvers confident and unhurried. The all-wheel-drive system provides added traction when roads get slick — something Wayne County residents know matters from November through March.

GMC Terrain SLE Features and Interior

Technology and Connectivity

The 2020 Terrain SLE comes equipped with GMC's 7-inch diagonal infotainment touchscreen with Apple CarPlay and Android Auto compatibility, making it easy to keep your navigation, music, and calls integrated without distraction. Bluetooth connectivity, a rear vision camera, and available 4G LTE Wi-Fi hotspot capability are all part of the package. The interior layout is clean and intuitive — something GMC got right on this generation of the Terrain.

Comfort and Utility

Inside, the Terrain SLE offers a comfortable, well-designed cabin with seating for five and a rear cargo area that handles grocery runs, weekend gear, and everything in between. The elevated seating position gives drivers a commanding view of the road — appreciated by buyers coming from smaller sedans. Rear passengers get a decent amount of legroom for a compact SUV, and the overall build quality feels a step above many rivals at this price point.

GMC Terrain Reliability and Ownership

The 2020 Terrain has earned solid marks from owners for day-to-day dependability. The 1.5-liter turbocharged engine, while occasionally flagged in early production years for oil consumption, showed meaningful improvements in the 2019–2020 model years. Most owners report routine, low-cost maintenance with no major mechanical surprises. The 9-speed automatic transmission shifts smoothly under normal driving conditions and holds up well over higher mileage. GMC's build quality on the Terrain is generally regarded as competitive with Toyota RAV4 and Honda CR-V alternatives — with a slightly more premium feel in interior materials and ride refinement. At 81,509 miles, this vehicle is entering what many consider its most cost-effective ownership window — past the steepest depreciation drop, with core mechanical components well broken in.
