Scrutineer Puns

A car salesman is trying to sell a truck, and finally someone comes onto his lot looking for a large work truck. The saleman greets the man, and the man immediately explains his need. The salesman directs him over to the truck. The man begins looking over this truck, scrutinizing ever detail. Eventually he turns to the salesman and says "the truck looks fantastic. Because i need to tow a lot of heavy equipment, i will not be buying the truck". The saleman is floored. "But sir, the truck has a wonderful engine, big enough to haul some of the heaviest of trailers and loads!" The man replies "yes, but theres just one small hitch".
