The 2021 GMC Sierra 1500. A premium pickup with professional-grade capability and a more upscale character than its Silverado sibling.

My favourite commuter ever

40 miles each way. The 2021 GMC Sierra 1500 makes the commute genuinely enjoyable. Seats stay comfortable, adaptive cruise works brilliantly, fuel costs reasonable. After 25,000 miles nothing has gone wrong.

Solid choice — does most things very well

Hits a sweet spot for me. Refined on the motorway, economical for commuting, practical for family. Only gripe is infotainment slow to connect to phone on startup. Build quality noticeably better than my previous car.

Decent, but not outstanding

Solid car that does its job without exciting me. Ride comfortable, easy to drive, safety features work well. Interior materials feel a step below the price point, engine noisy when pushed. Reliable but not class-leading.

Best car I've ever owned

I've owned many cars and the 2021 GMC Sierra 1500 is comfortably the best. Interior feels genuinely premium, ride is smooth, infotainment actually works. My only gripe is wind noise at motorway speeds — minor on an otherwise outstanding vehicle.

Good but expected more

Competent, reliable, comfortable. But 'competent' isn't what you want spending this much. Hard plastic panels in places, engine note unpleasant. Test-drive the competition before committing.

Absolutely love it — couldn't be happier

Picked up my 2021 GMC Sierra 1500 and have zero complaints. Build quality is exceptional, driving experience puts a smile on my face every commute. Fuel economy beats EPA estimates. Highly recommend.

Ongoing reliability nightmare

Fourteen months, more time at the dealer than my driveway. Turbo failed at 8,000 miles, infotainment blank at 11,000 miles, persistent vibration they cannot locate. First and last experience with this brand.

Resale value is remarkable

Just had my 2021 GMC Sierra 1500 valued after three years — depreciation far lower than I budgeted. Trouble-free ownership. A genuinely smart long-term buy.

Strong value proposition

At this price point the 2021 GMC Sierra 1500 is difficult to beat on pure value. Generous standard equipment, solid reliability record, and depreciation that won't sting too badly.

Exceeded every expectation

Nervous buying without testing more alternatives but after 18 months: not a single unplanned shop visit. Safety features have intervened twice on the motorway. Comfortable on long journeys, easy to park. Everything you want.
