Car on my mind...

It's really cool when you find a car you really want but you need to remember there are thousands of cool vintage cars around - so there is no rush.
On any early A body you will always have a lot more money into it than it's worth, this is ok since they are so inexpensive it usually won't be a fortune.
So I think you should let the "red mist" clear and take your time. Make a post that you are looking for some help from a California member to check it out and go from there.
