Am I Nuts?

I have recently have been looking to buy a Dodge Magnum RT. I know it has a plastic cheap looking dash and the front end is dated and kind of ugly. Not to mention the rust issues and the 5.7 valve spring problems.
But there is something that is appealing to me still and have always wanted one. The wife said she wouldn't mind driving one but it has to be in great condition with low miles. Hard to find.
She still thinks I'm crazy to pay that much for a 12 year old used car. Is she right and I'm just not listening? Talk me out of it.
