At the General Motors exhibit at SEMA, the 2009 Camaro convertible was given one of its first public showings. With the car definitely slated for production, this prototype drew more than its share of rapt attention, including from many folks in starched white shirts with pen caddies, holding tiny digital cameras and folding yardsticks, shooting photos from every angle and, when allowed, crawling all over the car, under, inside and out, taking measurements in order to create what may be their own company's future aftermarket parts to be ready for sale when this new Camaro hits the streets late next year. That's another big part of what SEMA and the SEMA Show is all about ... and something about which the general public rarely hears.
