Strange approach to booking

Let’s pretend that I have a car rental shop with 7 cars. And I have all 7 cars available for November. So the user will come to Sagenda booking and he will see that he has 7 cars for November 1st, 7 cars for November 2nd, 7 cars for November 3rd? Instead of choosing his preferred car (let’s say – Honda Jazz) and see the calendar with all Unbooked dates?

Another sample. User wants to book a car for 10-15th of November. Let’s say Honda Jazz. He has to select 5 bookings for Honda Jazz for 10, 11, 12, 13, 14 and 15 of November? 5 separate lines? Your system shows it like this.

According to my experience your system (in its Free version) is purely for yoga classes and doctor appointments. When user takes 1 appointment for 1 day and that’s it.
Using your system to book a car or house for 2 weeks will be very inconvenient.
Am I correct?
