IF at first you don't succeed, try again. This philosophy could apply to BMW and its second-generation 3 Series Compact, which shares little more than concept and name with its predecessor. Released in October 2001, the second generation, E46-based Compact range comprises the 1.8-litre 316ti and the 2.0-litre 318ti, while the 2.5-litre six-cylinder 325ti was added to the line-up in July 2002.
