Buying a 2nd hand Vespa

I want to buy a Vespa… reasonably newish - say 5-7 yrs old.

I searched previous threrads but couldnt find anything. So… does anyone know where are good places in Taipei to look for second hands Vespas?

Thx…

Dingzhou Road, just near the intersection with Xiamen St. There’s a shop run by a Mr. Ma. I’ve bought from him before and he’s great. The bike I got had a strange problem that everyone had problems identifying, but he took a lot of time with it and finally one of the guys hanging out in his shop for some other reason took it down the road, identified the problem, and Mr. Ma fixed it right away. No charge for any of the above, he considered it part of delivering a good bike for me.

He used to have a life-size advertising cutout of a horse outside his shop, but I don’t know if he still has or not. If you’re walking from Xiamen Rd. in the direction of Shita (basically) on Dingzhou, his shop would be on the left-hand side. Sorry I can’t remember anything more. You might want to search on “Ma” and “vespa” because I think I posted something about his shop earlier (when I had a clearer memory for where it is).
