BMW 330i ZHP
The E46 is slowly becoming a classic with those M3 prices going stratospheric. However, there is a hidden gem in the range. It is the 330i ZHP in a four-door guise. With a 3.0-liter straight-six engine that produces 235 HP and a six-speed manual transmission, this BMW is a proper fast and capable sedan.
The ZHP package includes a stiffer suspension and several other improvements. Interestingly, some drivers say the 330i ZHP is really an M3 with two more doors.
