A while back I used to take the heads out of the helmets and use only the helmet on the car. . .I did it for Senna and now am glad I did.
Faces are not that hard to do, I think I'm up to a six year old level now!
For my Tamiya Puegeot 206 I did the best I could, then mucked up the windows so you can't see inside very well. I also hid some bad decaling on my part with mud splashes.
I have found some "vintage helmets" but those were for circa 1950-1960. . .

I know it's only rock and roll, but I like it.
