I should have let someone else do it...

A few weeks ago, the forklift we use in our day to day operation stopped working. The battery died. The service company came and left a rental, hauled the old one off to their shop. Repair estimate for the battery was $5,200 for a new one. Rebuilt battery was priced at $4500. This lift has been satisfactory so far, but recent changes in our product line indicated the need for higher lifting capacity.
The owner of our company asked us to investigate the cost for a replacement unit with the needed upgraded capacity. I spent quite a bit of time researching options. They were presented to our owner, who indicated his desired choice. A used Nissan forklift for $9,500. It was shipped from New Jersey to the local equipment dealer and repainted. We waited until the ice and moisture on the roads were gone and the lift was delivered yesterday.
It didn't work coming off the flatbed wrecker. A mechanic is supposed to come (as directed by the dealer) today to check it out, although the conversation I had with the dealer indicated "it was working perfectly when we had at the shop."
It has already been paid for.
I am sensing the coming of a battle over this.
I knew I should have let someone else deal with this whole thing from the start.....
No risk, no reward, right?
