It runs and has a plow.  Looks like it might be a good price.

“1956 WIlly’s in as is condition, runs great, looks ok.. we never registered this only used as a yard machine, so have no title on it, previous owner did not register either, so no old registrations for paperwork other than bill of sale. still has some original features… I am listing this for my husband and he did not give me alot of info… has original motor… we use it to plow with.. any questions please call in the evenings when he is most likely home, tho he does not work a 9-5 job, but I can get answers and get back to you.. price without plow is 800… call 603 673 1361 or email.”
