When you look at the cars that are coming out of Detroit today, it wouldn't be surprising if you find them a more than a little bit disappointing. There are a lot of ugly crossovers that are full of incredibly advanced but completely unintuitive interiors. Nothing's simple enough for the average Joe to maintain, either. There's also a near-total decline of muscle cars. Detroit seems to be fairly allergic to the V8. That's a shame, because these old-school engines are brilliant and full of character.If you want an antidote to modern American machinery, your best bet is to dip into the classic muscle car market. That's where all the cars we're talking about here come from. The vast majority of them are very expensive, priced completely out of the means for regular enthusiasts. But, for those who can afford them, there's no replacement for what they offer. 1964 Pontiac GTO Average Used Value: $17,000-$75,000 (Coupe), $50,000-$66,055 (Convertible) MecumWhen people think about the Pontiac GTO, they usually think of the 1967–1968 version when it became a standalone model. The original 1964 GTO is not only worth talking about, but it's actually a bargain compared to the other cars on this list. A trim level of the mid-sized Pontiac Le Mans, the original GTO has a 389 cubic-inch V8 that was available in single 4-barrel and 3 2-barrel (Tri-Power) carburetor variants. The standard version produces 325 hp, while the Tri-Power version produces 348 horsepower.The 1964 GTO was available in 3 body styles: a hardtop coupe, a sports coupe, and a convertible. The convertible is the most desirable body style today, thanks to it being the rarest. Only 6,644 convertibles were produced in 1964, compared with 7,384 hardtop coupes and 18,422 sports coupes.MecumYou can get a coupe version of the 1964 GTO for as little as $17,000 still. That can go up to as high as $75,000, however. With the much more desirable convertible versions, you can expect to pay more along the lines of $50,000 for the lower end of the market and $66,055 for the top of it. If you play your cards right, you can get an affordable example of one of these and enjoy all the joys of classic muscle car motoring that a modern car can't give you, for less than you'd think. It'll also prove to be a great investment, as demand for them will only increase. 1970 Oldsmobile 442 W-30 Average Used Value: $44,500-$78,942 MecumThe Oldsmobile 442 is a muscle car that often gets left by the wayside in discussions. That's even though the W-30 version is an absolute powerhouse. It's powered by the 455 Rocket V8 with a few high-performance modifications (a high-lift camshaft, ported cylinder heads, and a cold-air induction system that took air in from directly underneath the front bumper). This gave it proper big-block muscle car power. It had a fair amount of weight reduction done to it, too. The distinctive scooped hood, for example, was made of fiberglass specifically to make the W-30 lighter.MecumThe 1970 Oldsmobile 442 W-30 (the pinnacle of the 442's performance) is one of the more affordable cars on this list. But, you'll still need to pay a lot of money to get your hands on one. You can expect to pay between $44,500 to as much as $78,942 for a W-30 these days. What you get for that money is a genuinely underrated muscle car that collectors will truly appreciate with time. It's also much more characterful than anything modern. 1965 Ford Mustang Average Used Value: $46,950 MecumThe original 1965 Ford Mustang is one of the most iconic and most important muscle cars ever made. It's now celebrated as a design classic, and its higher-performance V8 versions are still revered to this day by enthusiasts. While base model 1965 Mustangs only got a 120 hp inline-6, you could have as much as 271 hp if you chose the 289 V8. All that power feels completely analog, giving you a far more pure driving experience than even a modern Mustang GT or Dark Horse.MecumYou can get a 1965 Ford Mustang for around $46,950 now. That seems like a relative bargain for what it is, and you'd be right most of the time. But, some examples are selling for much more than that. It's not uncommon for immaculately restored or resto-modded examples to sell for over $100,000, or even over $200,000. But, if you just want a fairly regular and original 1965 Mustang, you can get something that's much more enjoyable than a current sports car from Detroit for a little less than you might have thought. 1970 Pontiac Firebird Trans Am Average Used Value: $85,905 Bring a TrailerA sibling of the Chevrolet Camaro (we'll be talking about a variant of that car later), the Pontiac Firebird Trans Am is one of America's most iconic muscle cars. That's especially the case with the 1970 model year version, which was the first year of the second-generation model. The 1970 Trans Am was only available with a 400 cubic inch V8, which came in Ram Air III and Ram Air IV versions. The Ram Air III produces 335 hp, while the Ram Air IV produces 345 hp. That made it one of the top performance cars in the golden age of Detroit's muscle car era, and one of the most desirable too.Bring a TrailerYou can expect to pick a 1970 Trans Am up for around $85,905. That makes it the first car on this list to venture into genuinely expensive territory. But, for what you're getting (a proper, all-analog muscle car), it's actually great value for money compared to the rest of the market. 1970 Dodge Challenger Average Used Value: $110,904 MecumThe original version of the Dodge Challenger has earned a place as one of the most iconic muscle cars of all time. That's likely due in large part to its starring role in the movie Vanishing Point. The 1970 Dodge Challenger was available with a wide variety of engines. This included the legendary 440 Magnum V8 and the 426 Hemi V8. The Hemi was the most powerful engine available, producing 425 hp and 490 lb-ft of torque.Bring a TrailerThe 1970 Dodge Challenger is the first properly six-figure car on this list, averaging around $110,904 on the used market. Incredibly clean examples are even selling for over $300,000 or over $400,000 now. It's definitely now far out of the range of regular enthusiasts. But, for collectors who crave that old-school muscle car experience, there really isn't a lot out there that's better. 1968 Shelby GT500 Average Used Value: $165,416 Bring a TrailerYou'd think the regular first-generation Ford Mustang would be good enough. Carroll Shelby clearly didn't, though, as he ended up making his own tuned-up versions of it. One of the coolest Shelby Mustangs ever has to be the 1968 GT500. This high-performance powerhouse is powered by a 428 V8 that was sourced from police interceptors of its day. That meant it had 360 hp and 420 lb-ft of torque. All this power was put to the road in the old-school way, giving it proper hair-raising muscle car characteristics.Bring a TrailerA 1968 Shelby GT500 will cost you around $165,416. That's not surprising, as it's one of the most collectible muscle cars on the planet. Get yourself one of these, and you'll have a proper analog Shelby Mustang experience that a modern Mustang just can't give you. 1967 Chevrolet Camaro Z/28 Average Used Value: $172,250 Bring a TrailerThe original version of the Chevrolet Camaro has become a classic muscle car for a reason. It looks great, the V8 versions of it sound great, and some of its variants are truly astonishing. That includes the 1967 Z/28. This was one of the first true performance variants of the Camaro, with a 302 V8 that produced 290 hp. It was also the start of the Z/28 badge, which carried through into modern iterations of the Camaro with the same high-performance focus as the original 1967 car.Bring a TrailerOne of these 1967 Z/28s will cost you around $172,250 on the used market. That's very expensive, but it could be well worth it. If you get one of these, you'll have an example of one of the most influential Chevrolets of all time. You'll also have a rawer version of that Z/28 performance, purer than anything you could experience in one of today's muscle cars. 1963 Chevrolet Corvette Sting Ray Average Used Value: $179,242 MecumThe Chevrolet Corvette Sting Ray is easily one of the most striking and most beautiful cars of all time. That's especially the case with the 1963 model year, which featured the split-window coupe body style. These split-window cars are incredibly desirable for a reason: they just look how an early '60s sports car should look. All 1963 Sting Rays came with a 327 cubic inch V8, and they could have as much as 360 horsepower if you went for the most powerful versions.MecumThe average used value of one of these 1963 Sting Rays is $179,242. That makes it one of the most valuable Corvettes out there. Considering how much people love the split-window coupe, that's really not surprising. A lot of enthusiasts will agree that this car is so much more gorgeous than anything Detroit could offer you today. 1970 Plymouth Hemi 'Cuda Average Used Value: $241,500 MecumThe regular Plymouth Barracuda is a criminally underrated muscle car. The Hemi 'Cuda builds on that by fitting the legendary 426 Hemi V8. That massive 425 hp engine turns the Barracuda into an absolute beast, easily putting it into the upper echelons of what muscle cars were able to do in this golden era of Detroit.MecumA 1970 Hemi 'Cuda will cost you around $241,500 now. That makes it one of the most expensive and most collectible muscle cars of all time. It's also one that delivers one of the most authentic big-block muscle car experiences. No modern car could even hope to match what the Hemi 'Cuda can give you. That's as long as you're able to afford one. 1969 Ford Mustang Boss 429 Average Used Value: $368,714 MecumThe Boss 429 has to be the ultimate version of the original Ford Mustang. Built entirely to homologate a NASCAR version of the Mustang that could dominate on track, this car is powered by a massive 429 cubic inch V8 that was expressly designed for racing. It was advertised as producing 375 hp. That's widely thought to be hugely underrated: it's estimated that this engine produced over 500 hp in its street trim.Bring a TrailerThe 1969 Ford Mustang Boss 429 is easily the most expensive car on this list. You can expect to pay around $368,714 for one. That puts it well into the upper echelons of not just muscle car values, but classic car values in general. You'll need to be a really wealthy collector to get hold of one of these. But, if you can, they deliver an experience that no modern car could ever hope to surpass.Sources: Bring A Trailer, Chevrolet, Classic.com, Dodge, Ford, Oldsmobile, Plymouth, Pontiac, Shelby American
