Biggest differences between 2011 Pro and 2012 or 2013

[M7kid]

I'm looking to purchase a Pro this season and have found a few 2011's that are priced real nice. This would be my first Polaris sled. What are the biggest differences between the 2011 and say the 2012 & 2013? I know they went to the belt drive in 2013, but anything else drastic? Bang for my buck, am I going to be happy with a 2011?

Thanks fellas.
