Journalists on this site have complained about how ugly and technologically complex recent BMWs have become. To that list I would also add a jarring ride, an overly aggressive throttle tip-in and jerky transmissions. Don't get me wrong. In the main, the propeller people's products still do exactly what it says on the tin: ultimate driving. But these defects make it difficult to drive most Bimmers smoothly, as one can an equivalent Mercedes, Audi or Cadillac (CTS). So when my BMW buddy nagged me to check out the 2008 650i coupe, I wondered: why bother?
