There are two RZ350s on eBay:
First one is an 84 with only 5k miles. Starting bid is $12k. Looks really nice, has a full fairing on it and some engine parts from Toomey Racing
Second one is a package of 3 RZ350s, sounds like 2 might could be restored and the third bike is mostly for parts. Bidding is at $9601 and 2 days left. They all looks a bit neglected, sat somewhere for a while.
