I am a little reluctant to give you all the details just in case you are disapointed as these deals seem to change all the time and I suspect that I just got lucky on the fuel policy. Perhaps they were just too lazy or didn't have time to fill the car up with fuel and so charge me a small fortune for the privilege?
What I would say is this:
Book in advance.
Shop around. I got my car via a broker. The broker got me a discount with the car rental company (I did check the usual rates for the company I used and they were more expensive). My rental agreement also showed this discount.
Check the terms and conditions very carefully both for the broker and the ones for the hire car company (as these often apply as well).
Check the fuel policy and their typical fuel charges.
Be wary of upgrading to a slightly bigger car; this may seem only a few extra euros but it will probably have a bigger fuel tank and so there is more opportunity to fleece you on the fuel.
Take out separate insurance to cover the ridiculous car insurance excess charges (otherwise you may find yourself a few thousand euros out of pocket if you write the car off). Taking out the rental car company's additional insurance is expensive.
Ask about any damage on the car before you accept it. Take photos of any existing damage on the car and make sure the staff know that you are doing this. There are several stories of hirers being charged for damage that was present before they hired the car.
Avoid insuring for additional drivers if you can. Typical rates seem to be about 5 euros a day.
If you are not going to drive many miles you may get charged for a full tank of fuel if you have the car for a week. One way round this is to take out several short term rentals. Usually the fuel policy will be different for short term rentals.
