Good: First four-cylinder AMG model produces 360PS from turbocharged 2.0-litre engine. Impressive handling and grip levels. As quick as you'd expect.
Bad: Expensive with a starting price of more than £37,000.
Good: High quality interior. Strong diesels. A250 AMG Sport 4MATIC the best of the range.
Bad: Handling not up to BMW 1 Series. Suspension a little on the firm side.
Good: Economical and practical. Interior quality and refinement improved. Pleasant, smooth shifting optional dual clutch automatic transmission does not suffer from same fault as DSG.
Bad: Not a sports car, so choosing 18-inch wheels creates a fidgety ride on rough roads.
Good: Much improved interior quality. More refined and better to drive than predecessor. C200 Bluetec is very impressive and economical. New six-speed manual.
Bad: Limited engine range initially. C220 CDI with automatic gearbox is disappointing.
Good: Well built and attractively styled. Available with low emission diesel engines. Entry-level C180 petrol is surprisingly good.
Bad: It's not as sporty to drive as you might think. Looks very similar to the saloon.
Good: Fantastic depth of quality. Lovely cabin ambience and improved interior space. Very refined, quiet and composed – even the four-cylinder diesels.
Bad: No 4Matic four-wheel drive models for the UK. Expensive options required to get the best from it. Only a minor luggage space improvement. Unintuitive infotainment interface.
Good: Most refined and comfortable small van on the market. Big improvement on the Renault Kangoo it's based on. 109 CDI BlueEfficiency returns a claimed 65.7mpg.
Bad: Rival vans are cheaper.
Good: Small and stylish saloon based on the A-Class. Better quality ride. Decent sized boot given its size. Well finished interior.
Bad: Not particularly engaging or rewarding to drive. Rear seats are only really any good for occasional use.
Good: Stunning estate version of the CLS. Has rakish coupe-like looks combined with 'shooting brake' practicality.
Bad: Top models are expensive. Exterior styling will not be to everyone's taste. Isn't the most engaging car to drive. Load space is awkward reach due to low hatch height.
Good: Big CO2 reductions. Four-cylinder CLS 250 CDI available at last. Precisely-built interior. Retains unique style of original CLS. Comes with full LED headlights.
Bad: Rear headroom tight for taller passengers. Options expensive.
Good: Distinctive and sharp looks. Excellent CDI diesels. Good motorway cruiser. Very comfortable and refined. Feels very well built.
Bad: Steering could do with more feel. Interior not as inviting as other premium saloons. Numerous reports of automatic transmission problems and software glitches.
Good: Elegant styling. Little top-down turbulence. Good selection of petrol and CDI diesel engines. Roof folds down (and up) on the move.
Bad: Not very exciting or involving to drive. Awkward shaped boot, Cramped rear seats. Springy manual gearchange. Four-cylinder diesels noisy with roof down.
Good: Classy and upmarket coupe. Superb C350 CDI engine. Decent headroom in the back. Good-sized boot. Supportive and comfortable seats.
Bad: Four-cylinder E250 CDI model is noisy and lacks refinement. Old fashioned touches like foot-operated parking brake.
Good: Well built and sharp styling. Huge and useful boot space. Comfortable long distance car. Excellent CDI diesels. Very refined.
Bad: Doesn't deal with corners as well as other premium estates. Disappointing smaller petrol engines.
Good: Huge road presence. Very exclusive and hand built to exacting standards. Bomb-proof reliability. Unstoppable off road but with a luxurious interior.
Bad: Only available through the Specialist Products Division at Mercedes-Benz World at Brooklands in Surrey. High list prices. Not designed for corners.
Good: Impressive ride quality. Available with two or four-wheel drive. Good rear passenger and load space. High quality interior finish.
Bad: Lacklustre dual clutch automatic. 220 CDI noisy and not as good as competitor diesel engines. Driving position not as high as other compact SUVs.
Good: Luxurious and spacious. The best big 7-seat 4x4 SUV. Adjustable air suspension standard. Outrageous performance from GL63 AMG.
Bad: They don't make parking spaces big enough. Unsuitable for the school run. Expensive to buy and run.
Good: New camper van from Mercedes-Benz built in-house. Will rival the Volkswagen California. Expect high quality.
Bad: Marco Polo Activity doesn't come with a sink, fridge or hob.
Good: More spacious and economical than before. High quality and comfortable interior. Great motorway cruiser. Impressive refinement.
Bad: ML 250 CDI engine can feel sluggish. 7G-Tronic gearbox not quick to respond. Poor in corners.
Good: S500 Sublime to drive. At 65g/km the S500L petrol plug-in hybrid is the biggest car to beat the 75g/km London Congestion Charge limit.
Bad: Extras can easily add £30,000 to the price.
Good: Sleek successor to CL bursting with high tech features. S63 AMG Coupe offers Ferrari performance in an opulent 4-seater coupe.
Bad: S63 AMG Coupe Starts at £125,000. S65 AMG Coupe starts at £183,000. Not as 'engaging' to drive as an S500.
Good: Impressively refined with a smooth ride. Metal folding roof means it's as quiet as a coupe. AMG versions are brutally fast.
Bad: Doesn't feel particularly special given the price tag. Comfortable rather than outright sporty. Steering lacks feel.
Good: High quality interior. Three roof options. Offered with 250 CDI diesel engine. Also available with 5.5 litre V8.
Bad: Not as good to drive as competition. Optional automatic isn't quick or decisive enough. High list prices. Avoid 18-inch wheels with 255/35 rear tyres.
Good: Stunning looks complete with gullwing doors. Amazing performance thanks to 6.2-litre V8 AMG engine. 0-62mph in just 3.8 seconds. Excellent grip and handling yet easy to drive.
Bad: From £157,500 but extras can soon add £20,000.
Good: Improved Sprinter gets sharper look. Engines more economical. Better interior comfort. Quieter on the move than before. Still the best van on the market.
Bad: Not a brand new van more a thorough revamp.
Good: Replacement for Viano. More premium than before.
Bad: Not coming until 2015.
Good: Drives tidily for such a large vehicle. Seats up to eight people. Classy feel inside.
Bad: Van-based looks are unappealing. Expensive. More of a minibus for corporate work than a versatile family MPV.
Good: Mercedes-Benz quality shines through with a comfortable and quiet cabin. Lots of configurations thanks to various lengths and roof heights. Strong engines.
Bad: Still has awkward foot-operated parking brake.
Good: Excellent quality and great to drive, Car-like refinement and cabin. Crew cab and minibus variants. Good standard equipment levels.
Bad: Foot-operated parking brake is a pain. 1.6-litre engine a little lethargic when laden. No high roof option.
