May need to sell my 31 model 57, 30k original mile barnfind, need help

I am looking for some advice, I am new to prewar cars and I have always wanted a model A or something vintage to ride my little girl around in, I bought a 31 model 57 sedan a few months ago from a friend that bought it from the original owners family, been in wyoming garage since 64, it has inline 8 which runs great, gauges work, shifts smooth, stops good, has original interior which is worn but complete, body is rust free other than surface rust, has dual side mount spares, spares need tires, car has new Coker whitewalls, car was originally all black and at one time body was painted blue, need opinions on pricing, this is a driver but a time capsule as well, needs restored or keep as it is, I am trying to post photos but so far no luck, I hope to keep this but if I have to sell it what is a good price to ask for it I can text pics or email

If you have recently just purchased this car you are the closest to knowing its value. If you need to sell offer it on ebay and the auction will set a value.
