While driving through town the other day, I noticed my neighbor had a AC 314D for sale. Interested, I pulled over and took a look at it. I later got in contact with him and he said the engine was recently rebuilt and so it was in good running condition. However it does not come with the deck, but does come with a front plow. The paint is pretty rough, and it needs a new seat bad. I'm looking to restore this, but he is asking $550 for it. I don't know how much these usually go for, but do you think that is a good deal or should I let it pass? What do you think it would be worth from the description?
