i want to get the maserati ghibli tomorrow at LAX for an event i'm attending sunday. is the best route to book a full size with the best code i can find and pre-pay and just bargain at pick up for the lowest upgrade cost at preferred desk. i know i've been quoted 75 or 100 per day to upgrade to mercedes c63 amg... i've read some places avis won't let the ghibli go for less than 250 per day. anyone know?
