It was aimed at the fleet market. You needed a car that was demonstrably lower grade than your boss.
Even stranger, the difference in price, when the NG9-3 was launched, between the 150hp 1.8t and the 175hp 2.0t was £1000. Our local dealer, now long gone, told me that they sold more 195hp Hirsch upgrades for £895 on the 1.8t than any other UK dealer, because they explained that you got 20hp more than the standard 2.0t and saved a few quid.
