When a dealer is ripping off the general public they need to be outed period! The dealer has made the conscious choice to be a disreputable business owner, therefore, they are the ones excepting the consequences. If they don't like the reputation they have made for themselves they should stop being a bunch of thieves. It's that simple.
I am very glad you disclosed the name of this dealer and the person at Kymco USA. We should have each other's back and help each other in situations like this. If we don't, with dealers like this, who will?
I hope things work out with your GT. I love mine and it would be a shame if you don't get to enjoy yours. Ride safe, mscmkr.
