Overall, the Bonnevilles have few inherent problems. Early ones tended to be a little cold-blooded, but most of those bikes were re-jetted by the dealers. If not, up the pilot jet a size or two and install a shim under the needle and you should be good to go. However, because the bikes are so easy to work on, they tend to attract inveterate tinkerers, so lots of them have been modified—often with pipes and airbox removal kits. This doesn't make them bad, but it may make them a less-desirable commuter. By the same token, Bonnevilles also draw lots of mature enthusiast owners (like yours truly), so used ones, even those that have been heavily modified, seem to be in better-than-average condition. On the downside, used Bonnies are scarce, so nice ones, regardless of year or model, command top dollar. That said, the '01–'03s tend to be more reasonably priced.
