I was surprised too when I got it. It was the first offer I made. I thought I was low balling but it was worth a shot. Now I wish I had put something lower just to see how I would have made out. But I am in no way complaining I got lucky and got a great deal.
BTW it is with Alamo. I've rented through tem before, the conventional way and never had a problem. I think I paid this for an economy car last time.
