PETROL CARBURETOR SUNGLASSES: Maybe its the thought of strolling by all the Corvettes & Camaros at the Gilmore Heritage Auto Show on June 5. Maybe it is that we just want more style. These shades we saw at the Petersen Automotive Museum site look sunny-day-at-the-car-show-ready. PETROL STYLE: There are several to choose from; the Gulfstream and the Enforcer are also plenty vroom-vroom. The Carburetor is priced at $150.
