The increase in the number of cars in Israel is not just causing more traffic on the roads, but a substantial increase in revenues for local garages, which have reported a six percent increase this year above 2006 numbers, research company BDI-Coface reported on Tuesday. Yet, while the country's estimated 5,080 garages are expected to earn NIS 11 billion this year, the sector's 26,700 employees earn only NIS 6,800 a month, 13% below the average wage in Israel, BDI said. Almost one quarter (24%) of all the garages in Israel are concentrated in three cities - Jerusalem, Tel Aviv and Haifa, BDI said, noting that in 2007, 50 new garages opened across the country. The report also said that Israeli mechanics imported approximately $343 million worth of new parts in 2007, a jump of some 15% from 2006, when they imported $297m. worth. Meanwhile, in BDI's recently released business risk index, the car repair industry was rated as "very-high" risk and assigned a risk assessment 8% higher than the average 6.35 risk rating. According to the risk report, 21% of mechanics were placed in the "above-average" risk category, compared to the 15.1% average in other business sectors.
