328I Introduction:
The 328i model, featuring the M50B28 engine, replaced the 325i in the US market for the 1996 model year. However, the manual covers the 1992 model, implying it may be a transitional or early introduction, or the product name might be slightly misaligned if it truly is 1992 *only* for the 328i designation in all markets. This manual likely covers the M50 engine variants leading up to the 328i.
Manufacturing Locations:
Germany (Dingolfing, Munich), South Africa, Mexico (for North American market)
