I have a 2010 A5 and live in Colorado, where front plates are required. Has anyone tried the "Flexyframe"? They are designed to not only mount your front plates, but also protect the bumpers from light bumps, etc. Would require drilling holes in bumper, but also would avoid the expensive and ugly frame that comes from Audi. They have both "LD" (light duty) and "HD" (Heavy Duty) models, cost is approx $20 for LD and $35 for HD. www.flexyframe.com Any advice or opinions?
