I can not help directly as I am near Seattle but have a couple of comments. In a request like this I suggest you give more information, and Cadillacs have been around since 1903, and Montana is a very large state. I suggest you give year and model of car and general location. Could be close to three other states for example depending on where in Montana. I have done this gratis and would be glad to if it were closer. I have also flown to location to verify condition and value of a few vehicles I purchased and drove one home and had the other one shipped and passed on one also. Not knowing where you are or where the car is or the year the of the car is not helpful. Possibly a local club member could help if we knew a little more?
Good luck!!
