I will agree that most of the people who do models like muscle cars, lead sleds, or 50's-60's cruisers. I drive a lowered Civic daily. I have a CRX prepped for high performance drivers ed and I'm in my late 40's. Do I fall in the punk kids category? I do like me some muscle cars, mainly Mustangs, but almost any nice one will do. My model interests sort of run the gamut, but lean towards European and Japanese cars, muscle cars and a few early 60's sedans. I do think the may be a bit of the good 'ol boy's club exclusion going on in the model car shows. But as others have said, build what interests you and enjoy the ride.
