Suggestions for an availability calendar plugin

I am in need of a plugin for my clients wedding car hire website. They have 5 cars which can be hired out at any one time (normally full day slots). I need a plugin calendar where the clients can enter in bookings of each car in the admin and ad additional notes and display an availability calendar on the front end, so users can see if the car they want is available.

Can anyone recommend such a plug in which can fulfil these requirements?

Many Thanks
