I am currently wanting too purchase 2 sleds. One is a 2004 Arctic CAt T660 That runs great with 1100miles and a 2003 Arctic CAt T660 with 1300miles for $6000 (for both). When we went to view the sleds the owner had started them both 1 and a half hours ago. When we came and tried to start the sled it wouldnt start at all. The sleds have been sitting for a while and the batteries were dead. The guy said he'd bring it to a mechanic on the weekend. The next day tho when he was in the garage he tried once again and it started right away again. What can be the issue? I'm scared of it braking again.
