Automakers seem to be pulling out all the stops for this year’s SEMA show, indicating that the automotive aftermarket is chugging along just fine. Both Ford and Chrysler have announced double-digit SEMA show cars, and even Chevrolet seems to be closing in on that number with the late addition of three cars to its SEMA booth.

First up is a 1967 Camaro, meant to pay homage to the very first Hot Wheels Camaro, which featured a “Spectraflame” paint job, side exhausts and redline tires. The full-scale car does what it can to interpret this, and sports a Kinetic Blue paint scheme (just like the upcoming 2013 Camaro Hot Wheels Edition), side exhausts and wheels trimmed with a red stripe.

In addition, the 1967 Camaro gets an emission-compliant LS3 V-8 crate engine, good for 430 horsepower and mated to a four-speed automatic transmission. Outside, the car gets shaved door handles, Hot Wheels badging and a hood that copies the design of the original car.

Inside, the custom vintage Camaro sports 2012 Camaro front bucket seats in white leather with blue accents, a leather-wrapped steering wheel, a silver perforated headliner, silver sunshades, and silver vinyl interior panels and trim.

If you prefer the modern Camaros over vintage ones, Chevy has added a Tony Stewart-designed Camaro ZL1 to its SEMA list. Wearing gray metallic paint enhanced with tribal and Smoke graphics (in flat red with silver pinstriping), Stewart’s ZL1 gets tinted headlights with sinister red halo accents and gloss black wheels with red accents.

Inside, Smoke’s Camaro wears suede door panels, black leather door armrests with white trim, a black suede-wrapped steering wheel and piano black trim. Since the stock ZL1 already makes 580 horsepower from its 6.2-liter supercharged V-8, it was kept in stock form for this build.

Finally, celebrity chef and all-around gear head Guy Fieri lent his design talents to a Corvette 427 Convertible Collectors Edition, sprayed in gloss black with yellow stripes. This is the reverse of the yellow with black scheme found on most of Fieri’s other Chevys, including 1968 and 2011 Camaro convertibles.
Under the hood is the 427 cubic-inch (7.0-liter) V-8, pulled from the Z06 and used for all 427 Convertible Collector Edition cars. In stock form, it makes 505 horsepower and 470 pound-feet of torque, so Fieri didn’t feel the need to up the output with engine mods.

The car does wear embroidered headrests, and it gets fender badging recognizing the Guy Fieri Foundation. We wouldn’t be surprised to see the car appear in a future episode of Diners, Drive-Ins and Dives, either.
