Greetings and welcome. I had a 2013 for about two years/8,000 miles. At 6' I found myself wishing for a couple extra inches (leg room that is). My solution was to remove the uncomfortable butt wedgie and rode with an Alaskan sheepskin butt pad. It cushioned the hard spot uncovered when removing the wedgie. The leg room increase was noticeable to me. I too was very pleased overall with the scooter, just couldn't resist trying something else.
Here is a link to a 2014 650GT listed on Craig's List Denver. I've already seen a drop in asking price from $5,300 initial posting.
