Sardar and Mileage

A sardar from Delhi had an old car which had run for over a
      1,00,000 kilometres. He wanted to sell it, but was not getting a
      good price because of its excess mileage.
          He approached a Madrasi friend of his and asked for help.
      The Madrasi gave him an address in Chennai (Madras) and asked
      him to visit a mechanic there. The mechanic would adjust the 
      meter so that it shows only 30,000 kilometres.
          The sardar thanked him and left for Madras. For a few days,
      the Madrasi didn't see the sardar. He assumed that the sardar
      would have sold the car.
          A few weeks later, the sardar came to see the Madrasi in 
      the same car. The Madrasi was surprised and asked - "What
      happened? Why have you not sold your car yet?"
          The sardar replied - "Why should I? It has run for only
      30,000 kilometres."
