The 328 IS is probably one of the best series 3 ever built by BMW. The engine is very responsive, powerful and yet quiet. Gas consumption is outstanding. I actually make 32 m/g on highway and 26 on city traffic. The interior is very confortable and luxurious. Needless to say the 328 is very well built with lots of attention to details. Mechanically the 328 is as good as it gets.
Powerful engine, gas mileage, elegant exterior and interior design. The trip-computer is a plus.
