Look up mopedlar on here and give him a private message. I think he might have a few bikes for sale still. Not tomos, but you won't regret getting a bike from him. He has the best condition stuff at REALLY reasonable prices. One of the best people in this community no doubt.
Don't take this the wrong way but the newer tomos bikes are junk. Bad parts and shitty quality. Reliability is fucking garbage...If your dead set on a tomos look for bikes 2012 and older. I'd recommend one with the earlier a35 Reed valve engine, but the a55's are great too. Stay away from the a3's, smaller Piston pin makes top ends harder to find.
