Congratulations, that seems like a deal of a lifetime. I hope that you are getting a deed to the property and that your lawyer has done a title search. The sale contract should included "all contents". Taxes and insurance can be a nasty suprise. I had a small business 16 years ago I had to say the heck with it because of the cost of insurance.
There seems to be alot of nice tools and supplies in there. Get a file cabinet and find all the manuals for the shop tools. I hope that this is your dream shop. Good Luck, Rick
