THE coupe holds a special place in the hearts of BMW fans. The M3 coupe, for instance, has an image of outstanding power, balance and brutal style. Take a step down the tree and you find the 330Ci coupe, launched in September 2000, to replace the 328Ci. It is still coded E46 in BMW-speak which means the body remains the same. The big change is under the bonnet, where a new 3.0-litre straight six engine replaces the old 2.8. It makes a fine car better and undoubtedly continues that BMW tradition of building great coupes.
