Hi my name is Ryan and i have a 2006 Cobalt SS/NA 5sp Sedan. Bought it May 31, 2011 w/ 88000. It currently has 102000 miles. The only mods that have been done are Pioneer cd player, 12" Kenwood Sub, Aftermarket Headlights, Tinted Tail lights, Iridium Spark Plugs, Leather Armrest Cover & Boot, and Metal Shift Knob. Future plans include leather seats, suede door panel inserts, lowering springs, and maybe new carpet. I love the car so far even though the previous owner didn't take care of the interior well. If you have any ideas on what else I could do to my car, let me know.
