Used numerous times.
I own a car and use their service as a cab-replacement.
Pros
Good for short rides less than 2 hours.
Daily rate ($60) still cheaper than Enterprise(formerly Autoshare) ($65) and Zipcar ($79)
Customer Service is responsive by email, haven't had to call them yet like the other reviewers.
Great that you can reserve a vehcile for 15 min.
Cons
Need data plan and their app on your phone to use some cars.
I keep forgetting my username and password and have had to reset it 4 times so far. We all have enough passwords to remember, not sure if they can make it easier to identify users.
Can't end trips outside of Home Area, not sure if they have plans to expand Home Area in the future.
A bit tricky in terms of parking for example my street you can't park overnight so I can't end my trip there. You definitely need to learn your neighborhood and rely on the app to find parking spots.
Couldn't find the lever to tilt my seat in the Mercedes so I had an uncomfortable ride.
Protip - Membership cards aren't needed to start/end rides anymore.
Damage - No joining, monthly or annual fees.
$0.41cents per minute = $25/hour
