Good: 360PS all wheel drive A-Class with 450Nm torque developed for markets like China that tax cars with engines of over 2.0 litres very heavily.
Bad: Expensive, with a starting price of more than £37,000
Good: 2012 A-Class has conventional hatchback bodystyle. Competes with BMW 1 Series and Audi A3 Sportback. High quality interior.
Bad: Handling not up to BMW 1 Series. Suspension a little on the firm side: best on 205/55 R16 tyres. Do not be tempted by bling 18" wheels.
Good: Economical and practical second generation B-Class. Interior quality and refinement improved. Pleasant, smooth shifting optional dual clutch automatic transmission does not suffer from same fault as VAG DSG.
Bad: Not a sports car, so choosing 18" wheels with 225/40 R18 tyres is very foolish and creates a fidgety ride on rough roads.
Good: A big improvement on the previous C-Class. Feels well built and robust. Very comfortable and refined. High quality ride. Good CDI diesels.
Bad: Looks are heavy rather than svelte and graceful. Interior isn't very inviting. Steering is precise but lacks feel.
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: Neatly styled estate. Very comfortable and refined. Impressive CDI diesels are economical. Good sized useable boot space.
Bad: Parameter steering overlight in town. Expensive options. Not the best estate for driver enjoyment. Still has an old-school foot operated parking brake.
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: High performance in comfort. Top quality feel inside. A rare sight on the roads. AMG version is amazingly fast. More aggressive looking following 2010 facelift.
Bad: Expensive to buy and run. Depreciates rapidly. Very big for a two-door car.
Good: Stunning estate version of the CLS. Has rakish coupe-like looks combined with 'shooting brake' practicality. Available with efficient 250 CDI engine.
Bad: Top models are expensive. Rear end looks not to everyone's taste. Quite awkward to load because of low hatch height. 7-speed auto of C250CDI hunts at town speeds.
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 luxury interior. AMG version is an absolute beast.
Bad: Only available through the Specialist Products Division at Mercedes-Benz World at Brooklands in Surrey. High list prices. Not designed for corners.
Good: New small SUV to compete with the likes of the X1.
Bad: Not arriving until 2014.
Good: More spacious than before. Still has seven-seats. Adjustable air suspension comes as standard.
Bad: Very large. Petrol engines are thirsty.
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: New S-Class launched to an enormous fanfare in Mercedes Benz cathedral like permanent pavilion at the September 2013 Frankfurt Motor Show. At 69g/km the S500 plug-in hybrid is the biggest car to beat the 75g/km London Congestion Charge limit from July 2013.
Good: Wonderfully luxurious. High-class cabin. Superb refinement on the move. The best looking saloon this size. Improved again from 2010.
Bad: Feels as big as it looks. Sophisticated systems expensive to maintain and replace. Costly servicing and tyres.
Good: Sleek, luxurious new iteration of Mercedes S-Class / CL Coupe
Good: Impressively refined with a smooth ride. Metal folding roof means it's as quiet as a coupe. Available with clever Magic Sky transparent roof.
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 offered with 421PS/540Nm 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" 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: 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.
