Craig,

They are great cars if in proper running order. I don't know if you'll find one......but if you do make sure you know what your getting. A perfect car will cost $70,000 and up. A car that needs alot of work and paint etc, will cost in the $40,000 range but you will spend another $40K in restoration.
Let me know if you need any more help, as I own a perfect one (that is not for sale) and can tell you what to look out for.
