From 1986 to 1990, BMW built the M3 E30 as the base model for Group A racing. The M3 was a winner both on the road and in racing and has long since become a classic. Well-preserved examples are expensive and anyone who sits behind the wheel immediately understands the enthusiasm for the four-cylinder M3. This report portrays a rare special model "Cecotto" of the M3 and tells the story of the M3 of the E30 series. There is also a sound sample.
