The classic car bazaar is volatile at best – it rises and falls rather quickly, and gives no indication as to why a particular car has fallen out of favor. But it happens, the car that could fetch you six mighty figures can go down to five figures in just a matter of a few years. Even if it puts your grandfather-donated college-fund-on-wheels at great risk.

And for some, lackluster sales on their beloved classic cars suddenly take a turn for the better, turning their fortunes overnight. The reasons could be many but are mostly related to the eternal demand and supply ratio. Here are 15 classic cars receiving no love in recent years, with values taken from Hagerty.

15 1967 Mercedes-Benz 250SL

1967 Mercedes-Benz 250SL

A 2.5-liter inline-six engine powered this sport tourer, and with Bosch’s fuel injection, it managed a fairly decent 148 horses. The exterior styling was smooth, and the pagoda-like hardtop was removable for a more stylish ingress and egress.

Produced for just one year, only 5,200 of these were made – making these a super rare model that gave way to the 280SL. The monocoque chassis and those clean lines made it a good car, and it was getting good prices in 2017, touching almost $140,000 for the mint condition cars. Since then the prices have fallen through, with current mint condition cars going for as low as $110,000. Wonder why no wants these anymore?

14 1966 Dodge Charger

A 1966 Dodge Charger is a good car – a rather large two-door fastback on a 117-inch wheelbase that had four bucket seats, it delighted the horsepower-crazy people of the '60s. That said, not many Dodge Chargers were selling all that well in 1966.

Compared to the more than 600,000 Mustangs sold in 1966, only 37,000 Chargers made their way to new homes. Of course, there was nothing wrong with that 5.2-liter 230-horsepower generating V8 under the hood. That said, while prices for the 1966 Dodge Charger were going as high as $130,000, they have come down closer to $100,000 for 2019.

13 1975 Ferrari 365 GT4 BB

The 365 GT4 Berlinetta Boxer gave a cool 360 horses on a 4.4-liter flat-twelve power mill and was superior in performance and style. The move from the V-engine to the flat shape gave this mid-engined car better handling and balance. The Pininfarina wedge body looked gorgeous, and the car’s low profile, as well as the longitudinally mounted engine, complemented each other.

Perhaps that's why values for this classic car reached as high as $750,000 in 2016-17. Since then, either too many have flooded the market or public interest has moved to other models because this can now be had for as low as $500,000.

12 1969 Buick Wildcat

The 7.0-liter V8 under the hood of this wild cat made a super cool 360 horses, and this was one superior car from the Buick stable. The 1969 Wildcats were based on the Lesabre body but boasted bolder looks along with those “gills” behind the front wheels.

Positioned slightly behind the Le Sabre, the Buick Wildcat was still a good car and should have commanded decent prices on the car bazaar. For the past 4-5 years, this classic car seems to have stabilized on these for $10-12,000 a pop – which is hardly something to take home to momma. The low price could be because the Buick Wildcat isn’t as widely popular as say the Mustangs of that time.

11 1974 Lamborghini Countach LP400

Not for the faint-hearted in 1974 or now, the Lamborghini Countach LP400 was a supercar. With a 4.0-liter V12 engine, this made 375 horsepower and moved like lightning.

There have been models of this car, in mint condition of course, that have gone as high as $2 million a pop, but the recent years have seen the value decline to almost $1.3 million. That’s an incredible price fall in a matter of years for a car that many call an automotive icon. This was the first time that Lamborghini used those scissor-like doors, and the success was such that it carries over to the current models to date.

10 1976 Cadillac Seville

The Cadillac Seville was a rather small car offered by Cadillac from 1975. Fairly successful for its time, it was still not the kind of success Caddy hoped it would be, because not many could wrap their heads around a small but still pricey Cadillac car.

The 5.7-liter V8 power mill gave out 180 horses, and instead of being popular with the youth as Caddy had hoped the Seville would be, it became the favored ride of little old ladies. Still, a perfectly good car, the 1976 model can be had for as little as $3,000 on a high-mileage model and just about $10,000 for a mint condition one.

9 1984 Pontiac Fiero

Much like its name, the initial models of the Pontiac Fiero had some fiery problems with the engine, which were quickly covered by the dealer warranty, lest the news spread.

A mid-engined two-seater, and America’s only mid-engined two-seater at that, it was introduced in 1984 and stayed only until 1988. The 2.4-liter four-cylinder engine managed just 92 horses, a far cry from the sports coupe the Fiero was supposed to be. A fair condition 1984 Fiero can be had for as little as $1500, proving that old isn’t always gold. You don’t even need $10k to own a mint condition one today.

8 1966 Cadillac Eldorado

The 1966 Cadillac Eldorado two-door convertible was powered by a 7.0-liter 340-horsepower mill and spat out a cool 480 ft-lb torque. Paired with an automatic transmission, only 2,250 of these were produced for 1966 – making it a bit of a catch in the classic car bazaar. Or so you must have thought.

Surprisingly, you can have one of these for as little as $20k for a fair use model, and even a mint condition one won’t cost you more than $50-60k. The prices seem a little droopy for this, as does its future as a collectible. And we don’t know why.

7 1971 Lincoln Continental Mk III

A two-door coupe, the Lincoln Continental Mark III carried a 7.5-liter V8 under its hood, capable of making a cool 365 horses. The Lincoln Continental Mark III came to be when Ford’s VP Lee Iacocca directed the design team to put a Rolls Royce grille on a Ford Thunderbird – and you got to admit, the idea sounds cool.

When the Lincoln Continental rolled off the assembly plant, it looked fantastic. So how much do you think you can get one for today? Surprisingly, anywhere between $7,000 to $35,000 a pop – depending on the condition of the car. Not a huge profit maker on the classic car bazaar, is it?

6 1971 Chevrolet Impala

The 1971 Chevrolet Impala was 220-inches in length, and the biggest passenger car by Chevy till that time. That long and wide frame did not just make for a plush cabin, but also a very stable ride. At the time, prices ranged from $3,500 to $4,000 – and made the Impala a lot pricier than its previous years.

Sales went down a bit, though the 7.0-liter V8 made good on 245 horses. A beautiful and powerful car, the classic car bazaar does not appreciate it much – and you can get one for as low as $7,000 to about $16,000 for a mint condition piece. No love for the Impala now.

5 1949-1954 Pontiac Chieftain

All Pontiacs were redesigned in 1949 under the able guidance of Harley Earl, so done by Herman Kaiser. Now they were more in the league of the Oldsmobile and Cadillacs with elongated and widebodies and an OTT curved windshield, in two pieces.

The Chieftain looked spectacular with 3.9-liter and 4-liter engines that gave out 90 and 104 horsepower. For the late forties, and early 50s - this was a good car. Yet for the past few years, values have not gone up and are steadily but slowly declining. The interest in this classic beauty is fading fast.

4 1964-67 Sunbeam Tiger

With Ford vs. Ferrari doing exceedingly well at the Box Office, and the world yet again reminded of the greats if the 60s, Carroll Shelby and Ken Miles, its time to talk about the Sunbeam Tiger. Inspired by the success of the Shelby Cobra, the Sunbeam Tiger was made with Sunbeam Alpine shells; one designed by Shelby and the other by Ken Miles.

Rather zippy at first, perhaps the market was too small for yet another Shelby-like car to thrive. Interest in this rathe historical car is on the declines, with values dropping from $150,000 to about $125,00 already.

3 1952-1957 Lincoln Capri

In 1952, Lincoln tried to do what Volkswagen had done with the Beetle, but with a far bigger car. They slashed down the prices of the Capri, and also slashed the car size a bit. A far cry from the huge 1959 body, this Capri was shorter and narrower. Sales were slow but with the Capri proving its mark in races, things picked up.

In the classic car bazaar though, things have not been kind to the Lincoln Capri lately. A mint condition one can be had for almost $40,000 while a well-run one will cost you less than $10,000.

2 1946-1948 Ford Deluxe

Remember Greased Lightning from the movie Grease? Well, that was the Ford Deluxe, or as they called it at that time, the De Luxe Ford. The idea behind this car was to bridge the gap between the economy offering of the Ford standard, and the far pricier Lincoln lineup. The Ford Deluxe did come with many bells and whistles but was priced lower than the Lincoln cars keeping affordability in mind.

Recent year prices may not be on a free fall for this model but seem to hold steadily, with an ever so slight dip every year. The interest for this model isn't all that high anymore, with a mint condition car going for less than $25,000.

1 1976-1989 Porsche 911 Carrera (Turbo 930)

We are talking about the mid-70s here, the peak of the malaise era with muscle cars being turned into malnourished ones for better sales. Porsche did not care, and instead brought about an exhaust-driven turbocharger that further powered the 3.3-liter engine into going 0-60mph in 4.9 seconds.

This was the time when Corvettes could do zip 0-60mph only in eight seconds. Of course, this car was not without its faults with the turbocharged being a bit too moody and causing handling problems. But it was a commendable effort for that time. From a value of almost $300,000, this car is slowly falling to $200,000.
