In some cars, installing a new stereo requires cutting large holes in the dashboard. In others, you simply slide the previous stereo out and drop a new one in. That's the difference between cars that follow standards, such as including DIN slots in the dashboard, and cars with extensively factory-customized controls. SEMA, a show devoted to all the neat things you can add to your car, has a vested interest in automakers taking the standardized approach. It gives awards every year for the cars that are most friendly to aftermarket customization.
This year, the winners are Ford Shelby GT 500 in the car category, the Jeep Wrangler in the SUV category, the Chevrolet Silverado Classic in the new hybrid vehicle category, and the Toyota Tundra in the truck category. So, if you're looking for a car to customize, you'll just have to settle for a Ford Shelby GT 500.
