This is a decent car sharing option IMO. After giving up my car I pretty much rely on car rentals/car share services when the normal TTC won't do. What sets them apart from other car share options is pick and drop wherever within the area which can be a great option. Now I kind of plan ahead so always mark the spots I am going to leave their car so haven't had issues like citations etc to deal with yet.
I also like that all their vehicles have a GPS.
Now for the bad part the old four two are terrible to drive within the city as there is a notable lag in acceleration and sometimes I felt it the acceleration was even unexpected which is unnerving to say the least. The new four two fare a lot better. The four door options are a bit more expensive and drive like normal vehicles.
Hourly rates are a bit higher than the competition but I guess there is a premium to be paid for renting by the min and dropping the car wherever. Other bummer is that they don't allow you to drive out of the province/country.
I found their daily rates are a good value.
Something to look into if you want to dip your toes into the carshare pool.
