The car's hourly rate applies for each hour you have the car, until you reach the daily rate. The daily rate is the most you will pay for the car for any 24-hour period.
The daily rate applies to any 24-hour period from the time your trip started. So a trip from 9am one day until 9am the next day is one 'day' for the purpose of calculating the rate.
A car costs $5 an hour and $25 a day. A borrower will be charged for each hour up to 5 hours (5 x $5 = $25) and then the rate will be capped at $25 for the remainder of the 24-hour period. A booking of 5 hours, 12 hours, or 24 hours would all be charged the $25 daily rate.
Another car's rates are set to $6/hour or $60/day. This means the hourly rate would apply for bookings under 10 hours. Bookings of 10 hours or more would pay the daily rate.
This makes Car Next Door vehicles really economical if you need to get around town for a day (or more)! Check out this cost comparison against car rental and other traditional car share options.
Note that there is also a distance charge for every kilometre you drive, which includes fuel and covers the Owner for wear and tear.
