She called her friend for advice, and her friend asked how many kilometres she had on her car. She answered, “300,000 km”.
Her fried told her that was the problem. So the blonde went to the mechanic and told him to put it down to 70,000 km. A couple of days later the blonde’s friend asked her if she’d sold the car after rolling back the odometer.
The blonde replied, “why would I sell my car? There’s only 70,000 km on it”.
