From the North West, plan to get a M3. I work in Cumbria, live in Lancater / Wirral. CPO Tesla - CPO Tesla | Home This is the first build. It crawls the CPO listings every 10 minute and records them. I am hoping to detect and estimate trends in the availability and prices of used Model S'. I may also have notifications etc. at some point. Let me know what you think, anything else you would like to see added?
