Great story. I hope that parting words about buying Porsche's was said as a joke.
It's great that the owners achieved the outcome they desired, very positive; however I also think it's important to keep in mind that it will take some time for the buyer to realize value from the acquisition. In my opinion that should be the metric of success, did the acquired company create value, not for the previous owners/investors through an acquisition, but for the current and future customers through it's operations. I think sometimes the idea the companies should create value-added as an ongoing entity gets lost in the discussion about the company's stock creating a return for the investors/owners.
