All engines have a longitudinal arrangement in a motive compartment and set back wheels in motion.
There was a model 320d (turbodiesel) dispersing to 100 km/h for 9.9 pages later. Thanks to increased by 60 mm to a track and on 30 mm to the wheel Sedan base it is very steady, however it caused modernization of a suspension bracket. Also the salon which is equipped with six auxiliary safety cushions is updated.

Top of a model range of the 3rd series - the Compartment of M3 with the engine of 342 hp.
At the end of 1999 after the Sedan, the Station wagon and Coupet of the third series the concern prepared a cabriolet for production. "Three" with soft top is made on the basis of Coupet, however a door, back wings and the back panel of a body found other plasticity - the cabriolet looks prompter, dynamic. The folding top is put away in a special container, and at desire (for example, during the winter period) this container can be removed and installed easily a rigid roof which is offered at additional expense.
