My mom just bought a used 2016 Mazda3 i Sport. I myself never cared about mods until I got my 2011 2 Sport, and now I want to help her get her car away from stock. She probably won't care about performance mods or fancy wheels, but any tire recommendations or efficiency mods that you could send my way would be helpful, as would be any tips that you could offer. I'm going to see her tomorrow to help her figure out the infotainment system. Her last car was a '97 Ford Ranger so this is easily the fanciest car she's ever owned. Haha. Thanks in advance for your tips!
