I am a big fan of Car2Go. I've written a very detailed review with pictures on my blog here: http://www.cheapdude.com/saving-money/car2go-toronto-review/, but will do a more summarized version for Yelp too.
Good:
- Cheap
- Less expensive than a taxi
- You can take 1-way trips
- Membership is only $30
- Great for getting around in the city
- Can even be cheaper than TTC
- Environmentally friendly when compared to many cars
Bad:
- Occassionally issues unlocking cars because they don't have satellite signal
- Finding parking can be difficult if you are going to an area where the lots only hold a few cars
- Though accessibility is growing, occassionally it can be difficult to find a car near you.
Overall, if you can put up with the bad stuff it is an awesome service for getting around the city without having to own a car, or as an alternative to your current vehicle. Always cheaper than a taxi and sometimes even less expensive than the TTC.
This would be bumped to 5 stars if you could park at any metered parking space or if they had more lots to use.
