The Chevrolet Series 490 (or Four-Ninety) is a Brass Era American automobile, made from 1915 to 1922 by Chevrolet. Introduced in June 1915, the 490 sold for $490. Chevrolet 490 was an immediate success and established the brand as a big player. The name would not denote the price for long (in 1921, the average price was $820), but it would stay low enough to take a chunk out of the Model T market. The Model T started at $495 at the time. Chevrolet was soon so profitable that Billy Durant began buying shares of GM stock with his Chevrolet stock. Electric horns were standard. And by 1921, standard equipment included a speedometer, and ammeter, dome lights (closed-body cars only), and headlight dimmers.
