The last 12 months have been stormy for the compact executive sector. With new arrivals such as the Alfa Romeo 159 and Lexus IS, plus the Cadillac BLS, buyers have been given a wider choice of talented and individual cars than ever. And yet once again the BMW 3-Series remains unbeatable. 
Its blend of driver appeal, build quality, desirability and low running costs gives it the edge over every rival. 
Its blend of driver appeal, build quality, desirability and low running costs gives it the edge over every rival. BMW knows exactly what makes buyers in this sector tick, as the 3-Series has few flaws.
Steer clear of the complicated iDrive option and the interior layout is easy to get on with, and no competitor boasts more rear legroom, meaning this car is every bit as practical as most family motors. Thanks to its resistance to depreciation, the blue and white propeller's contender is also highly cost-effective to run.
Great engines, crisp gearboxes and rear-wheel-drive dynamics mean the 3-Series never fails to entertain. Rivals may have narrowed the gap, but the BMW is still the best in the class.
Finally Alfa has a car to challenge rivals at the top of the sector. Although not as technically adept as the BMW, the 159 has more character than a transporter load of German rivals. That may not be a surprise, but Alfa has also improved in other areas. The driving position is faultless, running costs lower and accommodation more spacious.
Despite the onslaught of newer rivals, the Audi keeps its place here. Handsome looks and a stylish cabin give it great showroom appeal, while recent suspension improvements and new engines make the latest A4 genuinely enjoyable to drive. Good value and cheap to run, it's no wonder A4 sales go from strength to strength.
