Turn back your car odometer

A blonde made several attempts to sell her old car. She was having a lot of problems finding a buyer because the car had 340,000 miles on it. She discussed her problem with a brunette that she worked with at a bar.
The brunette suggested, "There may be a chance to sell that car easier, but it's not going to be legal.""That doesn't matter at all," replied the blonde. "All that matters it that I am able to sell this car."
"Alright," replied the brunette. In a quiet voice, she told the blonde: "Here is the address of a friend of mine. He owns a car repair shop around here. Tell him I sent you, and he will turn the counter back on your car to 40,000 miles. Then it shouldn't be a problem to sell your car."
The following weekend, the blonde took a trip to the mechanic on the brunette's advice.
About one month after that, the brunette saw the blonde and asked, "Did you sell your car?"
"No!" replied the blonde. "Why should I? It only has 40,000 miles on it."
