Hey all. Potential new owner of a Mazda 3, but trying to get the best bang for the buck. I've done some searching, but haven't found what I'm looking for. I'm looking for a 2012-2013 hatch, ideally the grand touring, but the prices are a bit extreme compared to other trims. The skyactiv is a must, but I'm open to trims if I can later upgrade to leather, power, heated seats (gf demands). Memory would be ideal. Not a stranger to a soldering iron or junkyard diving, but wondering if a certain trim comes with all the plugs, just unused? Or if there are guides to later implementing these features as stock-feeling as possible? Any help is much appreciated. Thanks!
