I'm looking at buying a roadster. It is a 2008 model that is reporting 169-171 mile range in standard mode. It has about 20k miles on it. That range seems low to me, based on the study. The owner says part or all of the battery was replaced within the last year. Should I be concerned about that range being so low? I asked about logs, but I don't think the current owner knows anything about how to get them. Is it something that can be done easily without OVMS? One more question... Is there anything else to inspect or be concerned with when buying a roadster? It seems like the battery state is really the big one and if everything else looks and feels mechanically sound, it will likely be ok.
