Hello! I am rebuilding my credit from a divorce and was finally able to get a vehicle back in my name and it just happened to be a 2006 Lincoln Zephyr. I know nothing about Lincoln's and if anyone could lead me to some custom mods, or some performance upgrades then that would be great. I looked on the forums some and rarely saw anything for the 2006 Zephyr. Also, does anyone know if I can upgrade the sound system? Give it a nav system, or even a backup camera? I am looking to try and do some minor upgrades to it. Any tips, tricks, advice appreciated.
