10 of the Rarest and Most Powerful Classic Muscle Car Convertibles

  1. 1969 Ford Mustang 428 CJ/SCJ Convertible

Ford`s best-selling pony car, the Mustang, got its third restyling for 1969 and grew in size. The new body was bigger and wider, but the wheelbase stayed the same. All three body styles were present so buyers could choose between the elegant convertible, standard coupe and sporty looking Sportsroof fastback. But the competition was tougher than ever and Mustang sales showed Ford that it needed to invest into Mustang to maintain its popularity.

The biggest news for 1969 was the famous Cobra Jet 428 V8 engine, which was available in two versions, the Cobra Jet and Super Cobra Jet (SJC). The difference was in several high-performance parts in the SJC. Interestingly, Ford rated this engine to a conservative 335 HP, but in reality, the output was closer to 450 HP. Mustangs equipped with this engine could see 60 mph in as little as 5.5 seconds.

The Cobra Jet 428 was available in all three body styles and with the GT package. As expected, they installed most in the coupes of the Sportsroofs, but 122 people ordered the mighty Cobra Jets and Super Cobra Jets in the convertible body style.

Out of that number, the rarest is the Q-code Super Cobra Jet without the GT package and with a manual transmission. They only build five of these cool looking, top performing machines.

  1. 1965 Pontiac Catalina 2+2 Convertible

In the mid-1960’s, the Pontiac GTO was the car to have since it was on the forefront of the exciting new muscle car movement. With its performance, powerful engine and great Pontiac styling, the GTO was the perfect car for the moment. But, it wasn`t the only stellar performance machine coming from Pontiac, and in 1965, there was another pure muscle car icon in form of the Catalina 2+2.

Behind this strange name hides a full-size Catalina model, available as a coupe or a convertible, but with a performance twist. The regular Catalina was a handsome, decent selling model, but in 2+2 form, it transformed into a true Gran Turismo with a luxury interior and fire-breathing engine. Since the Catalina was a full-size model, it was eligible for engines over 400 CID, according to GM rules of the time.

The Catalina 2+2 came with the famous 421 V8, and drivers could get the Tri-Power intake system. This power intake system was the same as on the GTO, and it could boost the car’s power to 376 HP. Car buyers could also order limited-slip differentials, heavy duty steering, brakes and a whole lot more, making the Catalina 2+2 well-appointed but unfortunately, expensive, too.

The top of the line 2+2 cost over $4,000 which was a hefty sum and much more than the similarly equipped GTO, for example. Pontiac produced around 11,000 of these fine machines in 1965, but only made around 200 convertibles, making the Catalina 2+2 rag top a rare find, indeed.
