hello

i am writing a business plan for a new car rental company based in
spain.  answers to the following questions and any links to info on a
breakdown of costs or business plans of car rental businesses in spain
(or europe) would be very helpful.

1. what percentage of visitors to spain hire a car for their holiday?
2. what is average length and cost of car rental in spain?
3. what is the size of the car rental market in spain?
4. on average, how many days a year is the average hire car actually
rented out for?

thank you
mark
