Hi James,

Production 1998-2006.

Such was the success of its older brother, when the E46 3-Series was launched it was clear that BMW were planning a vast array of engine and body style variant for this car. Tuners found it very difficult to decide upon which model they should purchase in order to conduct their development work.
