So, this is what I´ve been working on in the last few weeks. I´ve noticed that the carsets of the 50s were great but maybe the front part of the cars was not so accurate like the rest. So I´ve tried to improve it and make it look more real. There is still room for improvements but I hope it´s decent.

I didn´t touch the rest of the cars.
Like always feel free to comment, make suggestions, improvements, etc...
in the future I´ll try to do the other seasons aswell.
