An interesting article,
http://classic.autosport.com/news/report.php/id/134682 but I don't agree with this: "I've always thought that governors of any spec or near-spec series should feel obliged to make their cars visually appealing and that US open-wheel racing has been poorly served in this millennium, with the exception of the 2007 Panoz DP01 Champ Car.", I thought Lola and Reynard produced two great looking cars, like these two, pictured at 2002 Tecate/Telmex Monterrey Grand Prix.
