KABUL: (Reuters) - Afgha-nistan's booming car sales industry has been thrown into chaos by a growing aversion to the number "39," which almost overnight has become an unlikely synonym for pimp and a mark of shame in this deeply conservative country. Drivers of cars with number plates containing 39, bought before the once-harmless double digits took on their new meaning, are mocked and taunted across Kabul. "Now even little kids say 'look, there goes the 39'. This car is a bad luck, I can't take my family out in it," said Mohammad Ashraf who works for a United Nations project. Other "39" owners flew into a rage or refused to speak when asked whether their car was a burden.
