I am willing to be that the site doesn't get updated in time for people to actually be able to use it. I would suggest calling them directly (the person I spoke with the other day was very nice) at 800.845.3365.

As for prices, I have the book, so here are some of them:

• Group B -- Lancia Y 3 Door (no A/C, no radio) -- $36
• Group C -- Fiat Punto 5 Door -- $43
• Group E -- Opel AstraClub 1.7 DTI SW 5 Door -- $52
• Group G -- VW Passat 1.9 TDI SW 5 Door -- $68
• Group I -- Opel Vectra 1.8 Auto (only Automatic transmission available) -- $75
• Group H -- BMW 320 D 4 door -- $107
• Group L -- Mercedes E Class 220 cdi 4 door -- $117
  

Notes:
All prices are per day for 2-13 day rentals. One day rentals are significantly more expensive.
Rates include all taxes, including that pesky 10% airport pickup tax. They also include all mandatory insurances, but there are other optional ones that Avis will offer you when you pick up the car. (That's right, the rental is really from Avis, which is a good thing!)
There are other cars available, but those are some common ones. Ask for more details when you call.
There is a $150/200/Full rate cancellation fee, depending on when you cancel. So only do this if you mean it.

Also, we (4 of us) will be arriving on the 11:50am flight on the 28th. Anyone want to share the Water Taxi? And for those of you who have booked one already, who did you call to do so?

Seth.
