Bad idea? I have a prius with 180k on it and I'm not wanting to wait for the 3. I figure I can keep the prius and rent the telsa. If I could rent it 8 days a month, that would be enough for the car payment and insurance at $100 a day. I've been looking at used telsas on eBay and it looks like I can get an s for 55ish with low miles. I live in Austin and I don't think I'd have an issue being people to rent it as we get a lot of people in town for events. Thoughts? Renting it for 8 days and I get it for the other 75% of the month and get the car paid off?!
