Over the past three years, Optima has hosted its Search for the Ultimate Street Car competition in conjunction with the Ultimate Street Car Association, and this year it kicks off on March 17th at the Las Vegas Motor Speedway. But, don’t start detailing and prepping your street machine just yet – you need to hop over to USCA’s official web page to register for the event (in the source field below.) But, rest assured, you’ll be welcomed regardless of what you drive, even if it’s a modified 1978 Honda Civic or something much newer. That’s right, the competition is open to all years, makes, and models as long as your car is a street-legal performance machine, and sports a major OE manufacturer factory affixed production tag or plate. If you own a kit car or modern reproduction model, however, you’ll just have to sit this one out.
