Just a few months after BMW ended production of the historic and well loved Z3 the very same assembly line was retooled to produce the Z4. Like the Z3's before it, all 2002-2008 Z4's were produced at BMW's factory in South Carolina. The US market Z4's saw 4 different engines and 2 different body styles. The Z4 featured the same basic suspension as the E46 3 series. While some knocked the style of the Z4 compared to the Z3 there is no denying that the Z4 was a much more advanced vehicle.
