I've narrowed my search and found some Maxis that meet my needs (great condition, low mileage, etc.) but in the process have found some JC Penny Pintos which I believe also use the Puch E50 engine. The Pintos look like they have a beefier frame than the Maxi and appear to be well made. The Pintos I found are minty and a little less expensive than the Maxis. Any opinions on the Pintos?
