Hi, everyone--After over a year of searching, I recently bought a 2006 Base Xfire and after some interesting negotiations with the dealer, got them to replace the catalytic converters and windshield. I'm in the process of putting it together for road trips and have questions about several things. Has anyone ever put fog or driving lamps into the knockouts on the base model? What type of aftermarket floor mats have folks gravitated to? Any thoughts on a locking fuel cap (since the fuel hatch doesn't have an interior release, it seems fuel theft and vandalism are possible). Finally, I'm planning to repair/upgrade the audio system to accommodate digital and I'm not tech-savvy enough to really know where to begin. Thanks for taking the time to read this and offer suggestions. I've always loved Xfires and now look forward to sharing that with other enthusiasts! Father Bryan
