You will see the available SPARK cars on the map on the main screen in the app. You can find information about all the details: the price for short and long-term travel, battery level, etc.

If you do not find the electric car you reserved, but you see it on the map, it may be located in an underground parking lot. 

In case you see an electric car nearby, but it is not visible on the map in the app, it is probably already booked by another user or in session.
