Hi all,

I am trying to produce a UML component diagram for a car rental service.

Basically, customers can log onto the website and request a quote online. Then an employee will scan the companies and find the best quote, email this to the customer and it will be accepted or cancelled.

If it is accepted a booking will be made and the customer will be emailed a voucher in which they take to the airport to pay (no online transaction)

I have attached an image - can anyone give me any advice. is it ok/lacking or wrong!!?

This has taken an age so advice would be greatly appreciated.
