E36 Introduction:
The E36 generation replaced the E30 3 Series in 1990 (for European markets) and 1991 (for US markets). The 323i variant was introduced later in the E36 lifecycle, often positioned between the 320i and 328i in European markets, and offered as a specific model in others.
323I Positioning:
The 323i typically utilized a 2.5L M50/M52 engine, offering a balance of performance and efficiency. It was a popular choice for those seeking a step up from the 320i without the higher cost or insurance of the larger-engined models.
Manufacturing Locations:
Primary production in Munich, Germany; also Dingolfing, Germany, and Rosslyn, South Africa. Some assembly may have occurred in other locations globally.
E36 Production Years:
1990-2000 (sedan/coupe), 1993-2000 (convertible/touring), 1997-2002 (M3 Evolution in GT trim)
Car And Driver Best:
E36 3 Series consistently featured on Car and Driver's 10Best list during its production run.
Motor Trend Import Car Of Year:
While specific 323i models might not have direct awards, the E36 generation was highly regarded by automotive press.
Overall Reputation:
Highly respected for driving dynamics, build quality, and performance, though some specific common issues require attention with age.
