Well, the fixtures are not really worth that. They've depreciated through use. The recoverable value is probably next to nothing, since (as I understand it) cigar stores are not exactly popping up all over the place. Assume a value of zero, or less than zero, for the store (in order to repay liens).
Likewise, "going out of business" businesses tend to liquidate inventory. No doubt he's already done so. The inventory valuation is probably well off, and the real value is going to continue to drop until the store is sold. Since he's decided to go out of business, he probably hasn't re-ordered (why would he?) from his wholesale suppliers, which means that you get a store full of slow movers and a need to replenish inventory to a significant tune.
Finally, the lease may be up or increasing dramatically (hard to imagine in the middle of a recession, but four stores in Swarthmore's 1-block downtown were just forced out). And the market might be falling, say because of antismoking bylaws. You also don't have his side businesses to create non-cigar cashflow through the use of the office space.
You could probably come up with a better turnkey offer once you look at his real-live balance sheet, which should list the depreciated value of assets. Likewise, you're going to have to talk to his banker beforehand, so do so early. Etcetera.
