Good: Second generation 1 Series has more efficient engines. 116d Efficient Dynamics averages a claimed 74.3mpg and emits 99g/km. 125d offers amazing performance and economy.
Bad: The looks take some getting used to.
Good: Neat folding lightweight fabric top, high quality interior, impressive handling even with the roof down, great diesel engines.
Bad: Not the best looking convertible around, limited rear seat room.
Good: Good looking sporty alternative to the standard 1 Series, super quick 135i, strong and efficient diesels.
Bad: Tight in the back for taller passengers.
Good: 320d Efficient Dynamics manages 109g/km of CO2, 68.9mpg and can really do that. 328i is the star of the range.
Bad: Extras can easily add £10,000 to the price.
Good: Smart looks, excellent engines, practical metal folding roof, decent luggage space can be augmented by lowering rear seat backrests.
Bad: Optional extras can quickly add up.
Good: Stylish four-seater coupe, comes with a great choice of engines including frugal diesels, 335i is outstanding.
Bad: Tight in the back for adults.
Good: New stylish hatchback version of the 3 Series. Gets more practical load area, extra rear space and a softer ride.
Bad: £1,300 more than 3 Series Touring, £2,600 more than 3 Series saloon.
Good: Station wagon based on the best car currently in existence. Every single fault of the E90/E91 has been addressed in the F30/F31. Nothing else gets as close to perfection, including £200,000 supercars.
Bad: Diesel engine stop/start system can be gruff.
Good: Effectively the replacement for the 3 Series Coupe. Longer wheelbase means more interior space. Will also be Convertible and Gran Coupe versions eventually. Best looking BMW in the range.
Bad: Firm ride on larger wheels.
Good: Simply the best executive saloon on the market. Refined and high quality interior. Great to drive with a forgiving ride. Remarkably efficient 520d. Five-star NCAP crash rating.
Bad: Steering doesn't quite have the feel or weight you'd expect from a BMW.
Good: Refined and spacious alternative to a 7 Series or an X5. Usefully large boot with clever twin opening. Very comfortable and quiet with great performance from all engines.
Bad: Doesn't handle as well a 5 Series saloon. Unusual styling looks awkward from certain angles. Limited rear visibility.
Good: Great to drive with a perfect blend of handling and ride comfort, top quality interior, very refined at high speeds, great engines including very efficient 520d.
Bad: There are other cars in the class with larger boot spaces.
Good: Sleek looks and more handsome that previous 6 Series, powerful yet economical 640d is an epic engine, high quality interior similar to latest 5 Series, amazingly refined.
Bad: More of a grand tourer than a sports car.
Good: Incredibly smooth and refined. One of the best convertibles at minimising wind turbulance with the top down. Very well equipped as standard. Good ride. 640d from September 2011.
Bad: Other convertibles at this level have a folding hard-top roof.
Good: Four-door version of the 6 Series is an alternative to the Audi A7 Sportback, available with the excellent 640d engine.
Bad: Prices start at more than £60k.
Good: High quality luxurious interior, huge amounts of space in the back, long wheelbase versions available, Efficient Dynamics means good economy and low CO2.
Bad: Too much tyre roar makes it probably the the harshest 'limo'.
Good: BMWs first hybrid matches the 535i for performance but with emissions of just 149g/km and low company car tax rates.
Bad: Not cheap at £46,860.
Good: Available as a range extended version. Impressive performance and handling. Superb interior design. Eight year battery warranty.
Bad: Styling is best described as 'complex'. Boot is a touch on the small side.
Good: Stormingly fast performance. Superb V8 engine sound. High quality interior. Great feelgood factor, yet still docile at low speeds. Available as coupe, convertible or saloon.
Bad: Not as involving to drive as an M3 should be. Analogue instruments too small to read quickly. Expensive to run.
Good: Immense twin-turbo 560PS V8 engine has more power than outgoing M5 yet improved economy. Thunderous performance. Huge amounts of grip and excellent brakes.
Bad: Not cheap at £73,000 and M Performance Edition an eyewatering £95,140.
Good: Massive power. 189mph top speed. Much better looking than predecessor. 28.5mpg combined.
Bad: High price.
Good: Compact off-roader available with two or four-wheel drive. Car-like to drive. Economical diesel engine with various power outputs. Usefully large boot.
Bad: Bland and ugly fascia, especially if factory sat nav not fitted.
Good: Low CO2 of 2.0 diesel thanks to start-stop system. Bigger and much better than previous X3. Good quality cabin. Comfortable ride. Six cylinder engine option from mid 2011.
Bad: Stop start does not work below three degrees centigrade. Originally best in class meant a long waiting list.
Good: Third generation X5, now offered with 4 cylinder as well as six cylinder and V8 engines.
Bad: Though only 149g/km CO2 in 2WD form, few people likely to buy the X5 25d sDrive.
Good: Unique coupe and 4x4 style. Drives and handles astonishingly well for a big SUV. M50d has monstrous 381PS and 740Nm torque, yet 199g/km CO2.
Bad: Far from nimble. Not as practical as an X5. Intimidating to other drivers. Think carefully about the image it will portray of you.
Good: Stylish and refined roadster coupe with folding hard top. Strong performance from 6 cylinder engines. Much improved steering feel came as part of 2013 revamp.
Bad: Top sDrive 35i 340PS engine is expensive, but not compared to a 340PS F-Type Jaguar.
