Life-Like Proto 2000 Series Ho Scale Mather 40' Single Deck Stock Car Train Box

I purchased at an estate sale a lot of toy train parts and it appears that all items may be intact. But I am not a train collector, therefore please ask questions pertinent to this auction before buying. This is a Mather 40' Single Deck Stock Car in original box.  It does not appear to have been disturbed from the tissue and I have not unwrapped it.  Please note, the box may show some signs of wear from age and storage. 

Please, please, please email me with any questions. Payment is expected within 5 days or the auction will be relisted. Thank you for looking and have a wonderful day.
