Shop the Newest GMC Models

GMC is widely regarded as the maker of some of the toughest and most durable trucks and SUVs on the market. Each and every vehicle that GMC produces is built to withstand tough conditions and shoulder any challenge you throw at it. You can also get supreme luxury when you opt for a higher trim level—like the famous Denali trim—on one of these vehicles, but at the heart of their design, each GMC truck and SUV has been built with capability at the forefront.

There are loads of great benefits to a new GMC. You will have access to the most up-to-date technology features for entertainment and connectivity. New models will come with available high-tech safety features enabled by sensors and cameras to keep you and your passengers safe no matter where the road takes you. There’s also the added benefit of being able to customize your new GMC to your exact specifications; you can add packages, pick trim levels, and select the engine that balances how much power you need with fuel efficiency to help save you money at the pump.

When you’re shopping for a new GMC model, check out GMC’s lineup of these popular SUVs and trucks!

The GMC Sierra

This full-size pickup truck will quickly make you the favorite among all your friends. Known for its excellent towing and hauling capabilities, you’ll be able to move significant cargo without an issue! This truck is great for household use or recreation as much as it is for taking to the job site. And if you like to get away on the weekends, packing up all your gear is a breeze, and towing a trailer is even easier! Look at the AT4 trim level if you want the best off-road capabilities.

The GMC Canyon

If the Sierra is a bit on the big side for you, check out a new GMC Canyon. This midsize truck is perfect for personal use, and its smaller size makes it a great option for regular driving as well as work use. Its better fuel efficiency means even commuters love it! It has excellent driving dynamics and is packed full of user-friendly tech to keep you entertained.

The GMC Yukon

Have you got a big family? Then, consider adding a new GMC Yukon or Yukon XL to your vehicle lineup. This full-size SUV can seat up to eight passengers, with additional legroom and cargo capacity in the XL version! You’ll never want for space when you opt for a new Yukon, and its mega-powerful engine selection will make sure that you can take the road by storm no matter how many people and how much cargo is in the back!

The GMC Acadia

This midsize SUV is smaller than the Yukon and is known for its smooth ride, comfortable interior, and high-quality appointments. It’s built to keep your family comfortable on the road with flexible seating options and intuitive infotainment technology. The Acadia has a refined silhouette and is a versatile companion for busy parents who need their vehicle for a variety of purposes.

The GMC Terrain

For people looking for all the power and capability they expect from a GMC vehicle but who want something smaller, check out a new GMC Terrain. This is GMC’s smallest vehicle and is their answer for a compact SUV, but it doesn’t suffer from a lack of performance. It can seat up to five people and boasts different efficient engine options. Its compact style and efficient powertrains make it a great budget-friendly option for people who don't need so much space in their vehicles!

The GMC Hummer EV

Are you a little daring? Want to break the mold? If you’re ready to venture into a new frontier, check out a new Hummer EV! This all-electric beast comes configured either as a truck or an SUV and is just as big and rugged as the traditional gas Hummers of old. However, these new models run on electricity, making them an excellent option for people who strive to live off-grid or simply want a vehicle that doesn’t rely on gas.

Shop Used and CPO GMC Models

Port Huron drivers can shop our selections of pre-owned and Certified Pre-Owned GMC models! We always have a great selection on the lot, though it’s always changing as used GMC models sell fast! If you get your heart set on a used or CPO model you see on our website, act fast because it might be gone tomorrow!

The benefits of shopping used are seemingly endless. While you can’t customize to your exact specifications, you get the benefit of choosing from features, trim, and packages from years previous, giving you more variety. You can also often get upgraded options at lower prices, meaning the overall vehicle you can afford might be even better than buying new!

CPO vehicles we sell undergo a rigorous vetting process to ensure they are of the highest caliber before we allow them into our program. They have additional guarantees and protections, making them a smart choice if you want many of the benefits of buying new with great discounts!
