the best collector trucks of the 1970s and 80sClassic trucks and SUVs are hot these days, and we've got a list of the models that are increasing in value the most. So, if you've got your eye on one of these awesome rigs, you'd better act fast or pay the price, literally.Everybody loves trucks, or at least it seems like they do based on how many are sold in the U.S. every year. Not surprisingly, this all-American love affair includes classic pickups and utility vehicles. Here are 10 trucks and SUVs that are really moving the needle these days, models that have seen their values increase the most over the last 12 months according to Hagerty. These figures are listed in increasing order and apply to vehicles in No. 2 condition, which is considered excellent.10. 1980 – '86 Ford BroncoAnd we start with a horse-themed Ford, but no, it's not a Mustang or Pinto, rather, the Bronco, specifically the third generation, which was built from around 1980 to 1986. This full-size, two-door SUV still looks great today and offers strong capability. Power is provided by a range of legendary engines like the 300-inline six and some healthy V8s. The median value of a model in No. 2 condition has grown a healthy 6% over the last year.AdvertisementAdvertisementWith Hagerty, you get insurance protection by enthusiasts for enthusiasts.

If you're not familiar, this little off-roader is the Suzuki Samurai. The 1986-to-'95 generation was an affordable way for folks to get out into the wilderness, to navigate trails bigger SUVs couldn't fit through. And just like the Bronco, the median value of a model in No. 2 condition has increased 6%.8. 1987 – '91 Ford F-Series PickupsPhoto by Hrach Hovhannisyan/Shutterstock.comPhoto by Hrach Hovhannisyan/Shutterstock.comAs we keep on truckin' through our list here, the next model is an actual pickup (finally!), not an SUV. Doubling the value increase of the last two vehicles is the 1987-to-'91 Ford F-Series. The eighth generation of these tough trucks was boxy and proud of it, plus the automaker offered these rigs with a huge array of engines and transmissions. I'd take a 300 inline-six with a manual gearbox, please. Regardless of my preferences, though, the value of these over the last year has grown by an impressive 12%, one for each month of the calendar.7. 1973 – '91 Chevrolet C/K Series PickupSlightly edging out the F-Series, our next truck is the third-generation Chevy C/K, which was offered from 1973 all the way until 1991. Predictably, over that incredibly long production run, these squared-off rigs were available with a dizzying array of different engines and transmissions. Similarly, there was no shortage of body styles, trim levels or interesting features. Over the last 12 months, the median value of a third-gen Chevy C/K in No. 2 condition has increased a whopping 13%.6. 1973 – '91 Chevrolet SuburbanOur next vehicle is a direct offshoot of the truck we just covered. The 1973-to-'91 Chevy Suburban is essentially an SUV version of the C/K. The seventh generation of this long-running nameplate was every bit as boxy as the trucks it was based on, but it also has room for the whole family… and then some. Honestly, these things still look huge today. As for the Suburban's value increase, it's gone up 13% according to Hagerty.5. 1974 – '80 Dodge RamchargerPhoto by Moab Republic/Shutterstock.comPhoto by Moab Republic/Shutterstock.comAdvertisementAdvertisementSo far, we've covered two Fords, two Chevies and a random Suzuki, but now it's time for a Mopar, and it's a good one: the Dodge Ramcharger. The first-generation model, which was offered from 1974 to 1980, is quite popular these days. Somewhat sleeker looking than the Chevrolets we just talked about, the Ramcharger SUV offered strong off-road performance and robust powertrains, everything from Chrysler's fabled slant-six to small-block and big-block V8s. The median value of an example in No. 2 condition, which is, again, considered excellent, has increased a whopping 15% over just the last year.4. 1984 – '90 Ford Bronco IIIf you want to go off-roading, but are reticent about dealing with some lumbering, full-size truck or SUV, Ford has an answer, or rather, had the answer: Bronco. Wait… didn't we just cover this horse-themed utility vehicle? Yes, we did, but now we're talking about the smaller Bronco II. Built between 1984 and 1990, this small vehicle was based on the compact Ford Ranger, not the larger F-Series. With that unmistakable '80s charm, these SUVs have seen their value increase 15% according to Hagerty.3. 1976 – '86 Jeep CJ-7Another off-roader people absolutely love, one that happens to be even smaller than the Bronco II is the Jeep CJ-7. Offered for a solid decade from 1976 to 1986, this rough-and-tumble SUV could tackle just about any terrain you could throw at it thanks to its advanced four-wheel-drive system and trim dimensions. As for values, they've increased 17% over just the last year, which is quite a hike, though that's nothing compared to the next two vehicles on this list.2. 1968 – '83 Toyota Land Cruiser FJ40Thanks largely to their quality, dependability, resale value and myriad other virtues, Toyotas are always super popular, though, we haven't had one on this list until now. Looking like some sort of offspring from a Jeep and a vintage Land Rover, the 1968-to-'83 FJ40 Land Cruiser is a legendary off-road-focused SUV that is tougher than a crate of hammers and even more useful. This SUV provides incredible capability and mechanical robustness, so it's no surprise values have been surging. According to Hagerty, over just the last year, they've increased by a whopping 30%! If you want a vintage Land Cruiser and don't feel like spending a fortune, you may have already missed your opportunity.1. 1979 – '92 Mercedes-Benz G-ClassPhoto by S.Candide/Shutterstock.comPhoto by S.Candide/Shutterstock.comAdvertisementAdvertisementAnd finally, we've arrived at the best collector truck or SUV that has seen its median value increase the most over the last 12 months according to Hagerty. And this magical vehicle is none other than the 1979-to-1992 Mercedes-Benz G-Class. A military vehicle offered as a civilian product, this SUV provides incredible capability and ruggedness in a handsome and surprisingly upscale package. In fact, the G-Class has even been used as the basis for a Popemobile. And if that's not enough of an endorsement, I don't know what is! The median value of an excellent-condition G-Class has jumped a whopping 45% over just the last year, so plan accordingly if you're interested in one of these tough vehicles.So, what do you think of these trucks and SUVs?
