What can you guys tell me about this car?

My wife and I have been looking for a house. Last night I went to one that has been on the market for 180 days (that I really liked BTW). It is owned by a widower that her and her husband custom built in the 1980s. She doesn't appear to be living there anymore. I checked out the detached garage and pole barn first as it was getting dark and wanted to make sure I could see them in the light. Then I went and checked out the home. The last thing I went to check on was the attached garage. I open the door and I see a car under a cover. Of course my curiosity was aroused. I could see the tires only and they were in great shape and knew the car had to be pre-1950s. I peeled back the front and saw the sticker shown in the picture #2 below. "Auburn Cord Duesenberg" I know zero about this car so I took some pics and looked some info up today. The license plate says "37CORD". So I guess I can safely assume it is a 1937 Cord.

I did some investigating this morning and saw a rusted junker sell for 22.5k. I couldn't find any values of complete models. This one is in great shape. He had a bunch of trophies on the wall from car shows.

Maybe I'll make an offer on the house and ask for the two cars in the garage as well. (The other was an S10 with a plow on the front for the long driveway). It does seem to be some sort of estate as it appears the widower has moved out. Perhaps she would be willing to sell everything as is? I wonder if there are any kids involved. If so you would think they would have the car out of the garage by now.

My wife couldn't come with as she got stuck at work so we are probably going to do a second showing this weekend.
