I have the opportunity to buy a 65 impala station wagon

Really just look for major rot or water I the oil. This is a friends 60 wagon he pulled out of Texas several years ago. Only thing he did to it was pull the carpet out ( was full of chicken crap) hose it out and left the carpet out of it. Satin cleared the original paint bagged it and wheels. Normal maintenance stuff to get it running. He has turned down 15 k for it.
