Make money renting your car while you travel
Like Airbnb for cars, FC's a peer-to-peer auto-sharing service from a trio of college dropouts (MIT, Harvard, and, ugh, Princeton) that lets you rent your car (and score free parking at Logan!!) while away on vacation, or on business, or at your cousin's graduation from ITT Tech
Here's how it works
Option 1: "List Your Awesome Car"After listing your ride and relevant specs on their site (it must be a 1999 or newer model w/ fewer than 150k miles -- and not worth more than $60 grand), call while en route before dropping it at their East Boston lot. After chauffeuring you to the terminal and potentially providing a goodbye hug, they'll wash your wheels and try to rent 'em. If somebody bites on your '04 Neon with a "fitful" transmission, well, consider yourself the proud winner of up to $20 a day, depending on how nice your car is. If not, well, then you just scored gratis parking (at $27 a day) for the duration of your trip to Cancun. Win. Win
