Is there such a thing as the perfect car? Likely not, but it's been claimed by many that the BMW
3-Series may just be the closest thing. Over the years, BMW has developed and evolved their beloved sports sedan (as well the coupe, convertible, and wagon variants) to a level that hasn't been matched by any other automaker - yet. Audi
is often seen as the BMW's most serious competitor with their A4 (and S4 performance model).
