In the world of Classic Cars, there always comes a point where certain cars will absolutely explode in value. Those price explosions are typically caused by huge demand for a certain car relative to how many of them are around. Predicting which cars are going to start being worth big prices on the used market can be a bit of a dark art at times. Some cars explode in value very quickly, while others will stay at the bottom of their value for ages before prices start rising.The classic car we're going to be covering is one of those cars that's not had a price explosion yet. But it is a car that'll definitely have one soon. It's beloved by enthusiasts and collectors alike, offers something that you can't get from a car in its class today, and is one of the most solid and easy-to-live-with classic cars around. Lots Of Cars From The '80s And '90s Are About To Gain True Classic Status BaTOut of all the eras of classic cars, the '80s and '90s are the ones that are poised to see an explosion in values. That's because these cars are starting to move away from being modern classics (or youngtimers) and into 'proper' classic territory. That's not surprising in many ways. Many of these cars are now 30-40 years old, and that's the prime age for a modern classic to start becoming a 'true' classic.One of those modern classics that's managed to start getting itself into true classic territory is a car that's now absolutely iconic. It's one of the most popular and most beloved sports cars of all time, combining the classic sports car formula with modern mechanicals. It's also still affordable... for now! The NA Mazda MX-5 Miata Is A Classic Car Collectors Are Buying Up While They're Still Cheap Via: Bring a TrailerThe original version of the Mazda MX-5 Miata has to be one of the most universally loved cars ever made. Based on classic British sports cars like the Lotus Elan, Mazda wanted to combine the driving experience of those older cars with the reliability and low costs associated with modern Japanese mechanicals. The result of that was this small, charming 2-seater convertible. Early cars have a 1.6-liter inline-4 that produces 116 horsepower, while later cars got a 1.8-liter inline-4 that produces 120 horsepower. That sounds like a tiny amount of power, especially by today's standards. But because the NA Miata is so small and light, it doesn't really need any more than that.The NA Miata may be bordering on true classic status these days. But it's still very affordable. Its average used value is $11,591 across all its variants. Those values are staying relatively stable, too. They're not going down, and they're not exploding upward either. All that adds up to a car that's a sensible investment, but still within the reach of the average enthusiast. Why Do People Want Them So Much? Via: Bring a TrailerWe all know how much the NA Miata is loved. So, why is that the case? What is it about this car that has absolutely charmed everyone who's ever driven one? Well, when you look at those reasons why, it actually makes a lot of sense why it ended up becoming one of the most successful sports cars ever. It's A Pure, All-Analog Sports Car With An Engaging Driving Experience Mazda The main thing that enthusiasts love about the NA Miata is its pure driving experience. There are no electronic driver aids or any other systems that can get in the way of you feeling and enjoying the road. The only real concession to driving ease is that it was available with an automatic transmission. Other than that, this car really drives like a modernized version of a classic European sports car.In a world where sports cars are relying more and more on technology and moving further away from that kind of raw, pure driving experience, the NA Miata feels like a breath of fresh air. That classic sports car style driving experience that people loved back when it was new is even more beloved now. It's Reliable, Cheap To Run, And Parts Are Cheap And Easy To Get Audrian Auto Museum The other big thing that has made the NA Miata so beloved among enthusiasts is that the ownership experience as a whole is very easy. That's thanks to it being very reliable, very cheap to run, and very cheap to fix. Because these cars are light and have small engines, they're very fuel-efficient sports cars. Parts are cheap and easy to get because they use the same parts as other Mazdas from the same era. That heavy use of proven '80s and '90s Mazda mechanicals also gives them that legendary Japanese reliability. Owners will talk at length about how reliable their Miatas are, often racking up huge mileages in them with very little problems at all. Other Classic Cars Collectors Are Buying Up Before They Explode In Value:MecumThe NA Miata is far from the only classic car that collectors want to get a hold of before they start exploding in value. All across the spectrum of classics that were new in the '80s and '90s, there are models that have bottomed out or started gradually going up in value. A couple of these cars are sports cars, like the NA Miata. One of them was even a direct rival to the Miata in period! A couple of the others, though, are as far from being sports cars as you could imagine. Porsche 924 via Bring A TrailerThe Porsche 924 has had an unloved reputation for decades. It was snubbed as a "poor man's Porsche" due to it explicitly being an entry-level model in its day. There's also the fact that its development was a collaboration with Volkswagen (resulting in earlier base-model cars using the same engine as the LT van) and that it has a conventional front-engined, rear-wheel-drive setup. The 924's time has come around, though. People are seeing past the snobbery from purist Porsche enthusiasts and are starting to buy them up and enjoy them. The faster variants are also genuine performance machines, with the 924 Turbo having over 170 horsepower and the rare Carrera GT having over 200 horsepower.Perhaps predictably for a Porsche, the 924 is the most expensive car we're going to talk about here. Its average used value is around $31,289 across all its variants. Realistically, you're going to end up paying a fair bit less than that for one of the more regular variants. Get a good 924 S or 924 Turbo now, and you're going to have a seriously great appreciating classic in your garage! Toyota MR2 (W10) Bring A TrailerThe W10 Toyota MR2 is the most similar car to the NA Mazda Miata among these choices. That's because it was designed under a very similar philosophy and was even marketed as a rival to the Miata when both cars were new! Like the Miata, it took inspiration from classic European sports cars and blended that with proven and reliable Japanese components. The big difference between the W10 MR2 and the NA Miata is that the MR2 is mid-engined. That gives it better weight distribution than the Miata, but it does make it more challenging for less experienced drivers.The W10 MR2 has an average used value of $13,582 across all its variants. If you don't opt for the incredibly desirable supercharged version, you'll realistically end up paying quite a bit less than this. The used values of these cars have been relatively stable for a long time and haven't yet exploded into true classic values. That price explosion is more likely to happen now than ever. If you've ever wanted one of these, it's definitely time to start saving up! Jeep CJ7 When you picture a classic off-roader, this is likely one of the vehicles you'll imagine. The Jeep CJ7 is a beloved classic for a reason. It's simple, reliable, can get you nearly anywhere you want to go, and has all the traditional charm of a 4×4 from an era that's now long gone. As a result, they've become very desirable. The average used value for a CJ7 is $21,002, and those prices aren't going down. If you're in the market for a classic 4×4 that's going to be a very solid investment, this is one of the best of the bunch. Dodge Ramcharger (Second Generation) Bring a TrailerThe second-generation Dodge Ramcharger is a car that often doesn't get talked about. It was one of the first cars that could be considered as being an SUV, and it's an old-school SUV at that. It's based on the Dodge Ram pickup truck of that era, and the truck engineering really does show through. That's especially the case with its engine choices—a 318 or a 360 cubic-inch V8. These engines came with a variety of transmission options, as well as a choice between rear-wheel drive or all-wheel drive.One of these second-generation Ramchargers will cost you around $18,389 on the used market. Very clean, low-mileage examples are starting to fetch over $30,000 or even over $35,000. People have started realizing that the Ramcharger is a great buy—if you've ever wanted one, make sure you get one now before those used values become astronomically huge.Sources: Dodge, Classic.com, Jeep, Mazda, Porsche, Toyota
