8: 1961 Chevrolet Impala SS
The Chevrolet Impala SS is an iconic car that has a huge following behind it, but when it comes to dedicated fans the ’61 model had some issues. The elongated body of the car had a tremendous amount of curb weight behind it, making the steering ratio troubling at best. Likewise, the performance of the original V8 engine has been outclassed by many cars over the years.
In the lowrider scene, 1961 is one of the most popular models. But as far as performance goes it’s lackluster at best. To be able to turn one of these things into a performance titan would take a lot of work and dedicated engineering. You can spend money better in a lot of other places when it comes to a 1960s performance car.
