Spare tire RAGE!!!

My 84 year old grandmother just bought herself a brand new 2011 Chevy Malibu. Last week, she was hit by some guy who came blasting through a red light and totaled out her mint condition Buick. So, she bought the new Malibu. It's a nice car and she's happy with it, but come to find out, it doesn't come with a spare tire or the jack to change it with! The dealer tells me that this is now an option on the Malibu. WTF? Since when is a spare tire an option on a car? I checked the GM website and sure enough, it's a $100 option. They never mentioned this to her when she bought the car and she didn't check to see if it had a spare tire. Honestly, I wouldn't have either. I've never heard of a car that didn't come with a spare tire. I bought a brand new Pontiac G6 in 2008. It came with a spare tire. So did the other 15 or so GM vehicles that I've owned over the years. All of them came from the factory with a spare tire. You didn't have to ask for it. It was just there. Not any more. So, she was going to pay the $100 for the stupid donut tire and the jack, but no. The dealer says that it is $500 to get the spare tire after you've bought the vehicle. You have got to be kidding me. It could not possibly cost this dealer $400 to have a donut tire shipped to Oklahoma and installed in her car. It's not like it's a complicated install. You put it in the freaking trunk! I had four tires and rims shipped to my house in Alaska last year. Alaska. It didn't even cost me $100 for the shipping. But they want $400 to ship a donut to Oklahoma and install it. And people wonder why GM sales suck. My mom and uncle who live in Oklahoma and near my grandma, are talking about going to a junk yard to find a spare tire for a brand new car. A junk yard. That's ridiculous. Any ideas on what we could do to get a better deal or how to deal with this situation? Are we out of luck? I just feel like my grandmother is being taken for a ride. Thanks for any advice!
