Many people think of the 3 Series as the quintessential sport sedan. The smooth and quick 328i is a delight to drive, with a refined powertrain, agile handling and a firm, yet supple and controlled ride. Fit and finish are excellent, but the cabin is snug. A stronger engine improves acceleration and still manages good fuel economy, but seat revisions reduced comfort. Agility, steering, acceleration, fuel economy, powertrain, fit and finish. Rear seat, some controls, cup holders.
