^Yes, but if course they are much more money because of it. An older model will do just fine but there is more weight over the nose due to the iron block, so it depends on your intended uses for the car. Also, the 13-14 body panels can be swapped to the older models if you prefer the look of the newer ones, I know I do
Either way you’ll be getting a pretty sick ride if you like the s550 cars.
