GMC’s Sierra is the slightly more luxurious and plusher cousin of Chevy’s Silverado. Since 1999, these two GM products have shared platforms, powertrains, and more. Today’s 2021 GMC Sierra 2500 Denali SEMA Build is from the fourth generation Silverado, which is the fifth generation Sierra. More interestingly, the current owner tells us that this truck is a SEMA (Specialty Equipment Market Association) build. With a mere 11,305 miles on the clock, this one-off truck could be your ticket to a super slick ride that’s a head-turner, and something quite special to behold.
The GMC Sierra and its stablemate, the Chevy Silverado, are well-known pickup trucks in the United States. The Sierra nameplate first appeared in 1988, as a rebadged variant of the fourth-generation Chevrolet C/K Series. These workmanlike pickup trucks are renowned for their no-nonsense demeanor, tough outlook, and impeccable reliability. Small wonder, then, that this 1997 GMC K2500 Sierra SLE looks so good, what with its mere 68,000 miles on the clock. The current owner says that the truck bears its original mileage, is up-to-date with servicing, and comes with two keys included at sale. So, if you want a classic vehicle that’s different, choose this 1997 GMC K2500 Sierra SLE.
The corporate cousin of the Chevrolet Silverado range, GMC’s Sierra line-up of pickup trucks is positioned at a slightly more luxurious point than its Chevy counterpart. Currently in the fourth generation of Sierra (which is the fifth generation of Silverado), the duo got a mid-cycle refresh in 2022. Changes included a revamped front end and an updated interior design, plus some tweaks here and there. That’s what you’ll be availing yourself to with this sub-34,000-mile 2022 GMC Sierra 1500 Elevation from Pompano Beach, Florida. It’s got the Elevation Premium Package, Elevation Black Package, X31 Offroad & Protection Package and a stout Duramax diesel under the hood. So, if you want a family-friendly truck that can take you further than where the tarmac ends, this is one fine option to consider.
The Chevrolet C/K Series of pickup trucks was introduced in 1960, and is the sister of the GMC C/K Series. General Motors knew that by sharing platforms, engines and other mechanical componentry across brands, they could realize synergies and enhanced economies of scale. This is seen today, with the Chevy Silverado and GMC Sierra duo. Here, we have a 1970 GMC C2500 Fleetside which comes from the second generation of the Chevy/GMC C/K-Series line-up. This era ran between 1967 and 1972, with the trucks assembled in a variety of places across the country. This particular truck comes from Hemingford, Nebraska and is a two-wheel drive variant, denoted by its C moniker. Furthermore, its 2500 designation tells us that it’s a ¾-ton truck. If you’re on the lookout for a classic American truck with some capability but in great condition for showing off as well, this is the ideal candidate to pick.

A brand born out of a request by Arnold Schwarzenegger. That’s perhaps how one could sum up Hummer. It all started around 1992 when Arnie suggested that AM General make a civilian variant of their tough and versatile military Humvee. Of course, when The Terminator makes a request, one considers it very carefully since refusal could be a rather ticklish affair. So, AM General created the Hummer brand and the H1 was the first product. However, the H1 was so massive that come the Two Thousands, AM General knew that they needed something a little more urban-friendly. Hence, the H2 of 2002, which was made until 2009. The H2 is relatively smaller than the H1, but still sits in the full-size segment. Over 153,000 were made, and we have one here today. This 2003 Hummer H2 has done 93,000 miles and comes to you from Cleveland. It’s got a 6.0-liter V8 and wheat leather upholstery. Oh, and it’s also got that impressive off-road capability that every H2 is renowned for.
