Tim! That's a great idea for a group. My daughter seems to have inherited my interest in automobiles. Her husband (a Ph.D), has NO interest in cars whatsoever, so she still calls me occasionally to discuss some auto she's seen on the highway. The last time I visited the two of them, he was marvelling at how we know makes and models, and older classics stuff as well.
I'll look for your group!
