In the UK, where I grew up, the E46 3-series was available with a Sport package from 2001 onwards. This added M-Tech suspension, an M-Tech II bodykit, sport seats, steering wheel and “M V-Spoke” Style 72 alloys (later replaced by style 135s). The revised bumpers and spoilers definitely lent the car a more aggressive, sporting edge and considerably enhanced the overall look of the car. The package, officially renamed from “Sport” to “M Sport” in 2005, proved immensely popular throughout the E46 production run. As a result, the UK used market is filled with relatively cheap examples. Not so in the US. When I moved here, I soon discovered that the American E46 did not receive the same package until 2003, and only then on the 330i/330ci models. Known here as the ZHP or “Performance Package,” this added all of the aforementioned upgrades plus redesigned camshafts and a remapped engine computer, supposedly bringing power to 235 hp (10 hp more than standard models). Ticking this option box added nearly $4,000 to the cost of the car, making ZHP-equipped models relatively uncommon. As a result, when used examples do crop up they seem to command a considerable price premium.
