2002 BMW 7-series

The Munich company's flagship sedan was nothing less than everything the company knew about car building, and that was quite a lot. Perfectly constructed, astonishingly fast and utterly besotted with technology, the big, gracious 7-series had but two flaws: The first was something called iDrive, a rotary dial/joystick controller situated on the center console, through which drivers adjusted dozens of vehicle settings, from climate, navigation and audio functions to things like the sound of the door chime. The reason for iDrive and similar systems is that designers were running out of room for switches and instruments. The trouble was that the iDrive was hard to work. Damn near impossible, in fact. Drivers spent many hair-pulling minutes driving to figure out how to add radio presets, for example, or turn up the air conditioning. When confronted with complaints, BMW engineers said, with barely disguised contempt: Ze system werks pervectly. Dis is no problem. Since 2002, BMW has gradually improved iDrive to make it more intuitive, but it's still a pain. The other flaw? The silly bubble butt, called the Bangle Bustle, after lead designer Chris Bangle.

2001 Pontiac Aztek

I was in the audience at the Detroit auto show the day GM unveiled the Pontiac Aztek and I will never forget the gasp that audience made. Holy hell! This car could not have been more instantly hated if it had a Swastika tattoo on its forehead. In later interviews with GM designers — who, for decency's sake, will remain unnamed — it emerged that the Aztek design had been fiddled with, fussed over, cost-shaved and otherwise compromised until the tough, cool-looking concept had been reduced to a bulky, plastic-clad mess. A classic case of losing the plot. The Aztek violates one of the principal rules of car design: We like cars that look like us. With its multiple eyes and supernumerary nostrils, the Aztek looks deformed and scary, something that dogs bark at and cathedrals employ to ring bells (cf., Fiat Multipla). The shame is, under all that ugliness, there was a useful, competent crossover.
