the 2010 Camaro had a couple oddities no longer in 2011 or later model 2010 Camaros.
GM Performance badge under the hood
GM Chicklet on front fenders
Flat weights on SS brembo brakes
Aqua Blue Metallic (best Camaro Color
)
Summit White was added to 2010 mid-year
Synergy Green Edition Camaro was available in 1LT fashion only (green seat stitching only unique feature)
Transformers Edition available across LT and SS trims (I think)
Late model 2010 2LT and 2SS models saw the addition of:
Parking assist system (with not so pretty bumper dimples)
2011 Changes that I know of
HUD for 2LT and 2SS
Synergy Green expanded to full lineup (without stitching or door inserts, but they can be bought through GM directly)
Upgraded PDM (Different voice, onstar mylink cell phone capability)
Rear defrost automatically comes on when freezing outside
Option of adding Convenience & Connectivity package to 1SS (finally)
Convertible added mid-year
