I built Curblane for my own cars. I run a small fleet out of Atlanta. I could tell you my gross to the dollar. I couldn't tell you which car was losing money, because that depends on the loan, the insurance, the parking and the cleaning, and none of that lives anywhere near the Turo dashboard.
When I finally worked it out properly, the car I'd have called my best was near the bottom. I'd been thinking about buying a second one.
Two cars are free with no time limit. When I had two cars I couldn't have afforded this either. I'm also the whole support team, so if it gets your numbers wrong, tell me and I'll fix it.
