I've been a fan of the 510 for awhile now but I couldn't find one in my area, found this 620 posted in craigslist and picked it up the same day. There are some rust spots but nothing too crazy. The interior is still in pretty good condition. Needs some new brakes but runs great. I'm not too sure how I feel about the rear wheel setup but they'll do for now.
(sorry about the boxes in the back I was cleaning out the shed at the time)
