We have a 2010 GRT late model. Car has been a back up but we are considering running it again a little more often. Was wondering if anybody has any feedback on the new updates available for GRTs and how much it helps the cars and what areas it helped the most. Just trying to decide if its worth the time an money at this point. Thanks for any and all info you can share.
