This leads to some rare models that have been overlooked in the market, which could be great for some drivers. These rare cars could be the showpieces you want to take to your local car shows and give the public something unusual and interesting to enjoy.To give you the most up-to-date and accurate information possible, the data used to compile this article was sourced from various manufacturers’ websites and other industry experts, such as Hagerty.

This Buick is a classy cruiser with real muscle under the hood, making it one of the fastest cars of its time. Most people overlook this car, but the price suggests some collectors are beginning to notice. Don’t be shocked if this car rockets to over six figures for models in good condition soon. Powertrain Specifications Using a massive 455 cu-in V8 engine, this Buick GranSport produces 360 horsepower and 510 lb-ft of torque on paper, but this was proven to be a vastly underrated figure. All this power goes to the rear wheels through a four-speed manual transmission or a three-speed automatic, which can then be translated into speed, such as a 0-60 MPH time of 6.4 seconds and a quarter-mile time of 13.3 seconds. The top speed for this Buick muscle car is 135 MPH; pretty impressive for 1970. 1967 Dodge Coronet R/T 426 Hemi Hardtop Average Price: $83,400 Mecum AuctionsThe 1967 Dodge Coronet R/T might be an overlooked muscle car, not only for its high valuation, but because it was the middle child. This model sat between the earlier 1965/1966 Hemi models and the venerable Super Bee that came in 1968. This led to the 1967 model being overlooked, especially when compared to the more popular Coronet 500, despite being a step above that model. Powertrain Specifications Power for this convertible Dodge Coronet came from the legendary 426 cu-in Hemi V8 engine that sent 425 horsepower and 490 lb-ft of torque to the rear wheels through a four-speed manual transmission. It didn't look like it, but the Hemi-powered Coronet was one of the fastest muscle cars of its day and boasted a 140 MPH top speed and a sprint to 60 MPH in the low 5 seconds. 1969 Mercury Cyclone Spoiler II Average Price: $52,500 Mecum This car was made for NASCAR. That was its intended purpose, and you can see that translated into the special aerodynamic design of the 1960 Mercury Cyclone Spoiler II. This Mercury came with an impressive engine, but that, along with its purpose, wasn’t enough to put it near the front of collectors’ thoughts when looking for muscle cars. The Cyclone is a mostly forgotten car, which means it could be one of the best muscle car deals you find. Powertrain Specifications An impressive 429 cu-in V8 engine powers the Mercury Cyclone Spoiler II. This engine attaches to a Ford C6 Long Ratio Model three-speed automatic transmission to drive the rear wheels with 335 horsepower and 440 lb-ft of torque. This car was capable of reaching 60 MPH in 6.1 seconds and had a listed top speed of 112 MPH, but was likely much faster in NASCAR garb. 1970 Dodge Charger 500 Average Price: $47,533 ShutterstockThe 1969 version of this car is extremely popular, but the 1970 Dodge Charger 500 played second fiddle to the R/T version. Officially, only the R/T had the 440/426 Hemi engine, which many drivers desired. Still, the Charger 500 wore a unique aero package that was designed for NASCAR racing. In 1970, this car was a trip option with the SE package. Powertrain Specifications The most powerful version of the Dodge Charger 500 in 1970 came with a 383 cu-in V8 engine and three-speed automatic transmission. This setup gave the car 335 horsepower and 425 lb-ft of torque, which is more than enough to send this car to 60 MPH in only 6.9 seconds. 1966 Oldsmobile Cutlass 4-4-2 W30 L69 OAI Average Price: $35,600 Hemmings Everything you want to know about this car is in the name. The Oldsmobile Cutlass 4-4-2 is a popular muscle car from 1966, but this configuration was rare and often overlooked. Only 54 models were made with the W30 engine to be used in stock drag racing. These cars were equipped with a 400 cu-in engine coded L69 and three two-barrel carburetors and an outside air induction (OAI) system with two cold-air snorkels. The OAI option meant the battery was relocated to the trunk. Powertrain Specifications The massive 400 cu-in V8 engine attaches to a three-speed manual in this version of the Cutlass 4-4-2. This setup produced 360 horsepower and 440 lb-ft of torque, giving this car plenty of power for some incredible drag speed. This large muscle car could reach 60 MPH in only 5.3 seconds and finished the quarter-mile in 13.9 seconds, making it one of the most impressive cars of the early part of the muscle car era. 1968 Pontiac Firebird Ram Air II Average Price: $26,225 MecumThe Ram Air II option was the answer to the beating the Firebird received in 1968. By this time in the muscle car era, the SS 396 Chevelle and Mopar cars were killing the Pontiac at the track. This led to the Ram Air II option, which gave more power with modified D-port cylinder heads. This car could be had with a 4.33:1 gear ratio and an automatic transmission, but fewer than 100 models had the automatic and fewer than 10 had the crazy gear ratio. Powertrain Specifications The 1968 Pontiac Firebird Ram Air II typically came with a four-speed manual transmission and had a high-output engine that measured 400 cu-in and sent 340 horsepower to the rear wheels. This gives the car enough power to reach 60 MPH in 5.1 seconds. The goal of this option was to make the car a drag race monster, and that happened, despite very few models being produced. 1959 Chevrolet Impala 283 Fuelie Sport Coupe Average Price: $24,255 MecumFuel injection isn’t nearly as new a technology as some seem to think. The 1959 Chevrolet Impala 283 Fuelie Sport Coupe had it, but it was rare to find this technology in cars during that time. The Fuelie was available, but it had less horsepower than the larger 348 W engine, which made it less popular during its time, thus creating a bit of a rarity. This resulted in a production run of less than 30 miles with the 283 Fuelie engine. Powertrain Specifications The 289 cu-in Ramjet V8 engine sent power to the rear wheels of the 1959 Impala through a three-speed manual transmission. This engine produced 250 horsepower and 305 lb-ft of torque, which wasn’t too bad for the time. Unfortunately, this power wasn’t going to blow anyone away in a heavy car, and this Chevy was only capable of reaching 60 MPH in 8.9 seconds on the way to 114 MPH. 1962 Pontiac Catalina 389 Tri-Power Four-Speed Convertible Average Price: $23,227 Bring A Trailer In 1962, Pontiac had large engines, such as the 389 cu-in model, but no GTO to put them in. This gave the Catalina line a few impressively powered cars using the Tri-Power setup. This is the name given to the engine with three two-barrel carburetors on top of the large V8 engine. This rare muscle car also had a Posi-Traction rear end. Powertrain Specifications This convertible Catalina came with a large V8 engine, as mentioned, and a four-speed manual transmission, which sent 348 horsepower to the rear wheels. This was enough power to get this big car going and send it down the line to reach 60 MPH in only 6.5 seconds. The top speed of this rare Pontiac is 134 MPH, making it a good car for anyone searching for fun and active performance on the road. 1971 AMC Javelin AMX Average Price: $15,100 MecumThe 1971 AMC Javelin AMX doesn’t get the attention it deserves and is certainly a rare find these days, especially since AMC hasn’t been part of the market for several years. The Javelin isn’t the first name that comes to mind because many collectors focus on the big brands, but this rare and powerful car could be a steal if you find one today. The price won’t stay low forever, making this a great choice when you want an unusual car to show off. Powertrain Specifications The Javelin AMX makes use of a 401 cu-in V8 engine that sends plenty of power to the rear wheels through a four-speed manual transmission. This car produces 330 horsepower and can accelerate to 60 MPH in only 5.8 seconds. The quarter-mile drag time is a respectable 14.4 seconds, which made it competitive during its time on the market. 1970 Chevrolet Nova LT-1 COPO Average Price: $14,900 American Muscle Car Museum It’s hard to say there’s an average price for this car because of its rarity. There might only be one 1970 Chevrolet Nova LT-1 COPO that wasn’t sent to Don Yenko, who utilized the Central Office Production Order program to sell some high-powered muscle cars. Using the right code, which was COPO 9010 for the LT1, this Chevy muscle car came with a much higher-powered engine than the regular Nova. The Yenko models are highly sought-after while those that didn’t go to Don Yenko are mostly forgotten and overlooked. Powertrain Specifications Power for this car came from the 350 cu-in small block LT-1 V8 engine that sent 360 horsepower and 370 lb-ft of torque to the rear wheels through a four-speed manual transmission. This gave the Nova enough power to rocket to 60 MPH in as little as 6.0 seconds and the ability to finish a quarter-mile run in the mid-14-second range.
