With these luxurious cars you stand a chance of having your cake and eating it too. Not only will you sit or lie in a cabin of unrivalled comfort, but you can even be doing so in a vehicle which has sensible running costs ?as company cars these just can鈥檛 be too silly to run. So, sit back and enjoy our top ten choices, from Audi to Rolls-Royce.

10, Audi A7 Sportback

Just look at those elegant lines, then look inside at that beautiful cabin. The tailgate gives easy access to the big and accommodating boot and, in this guise, you get a gorgeous V6 diesel for hardly more than the 2.0-litre four-pot.

Top choice: 3.0 TDI Ultra SE Executive S tronic

9. Rolls-Royce Ghost

The Ghost costs from £225,000 yet that does actually make it a bit of a bargain compared to the Phantom. For that you get one of the finest cabins known to man, and a 6.6-litre, 563bhp V12 which might tempt you from the back seat to the front.

Top choice: EWB

8. Mercedes CLS

The graceful lines of the coupe are not just for the Audi A7. Here they adorn a car that鈥檚 just that bit more enjoyable to drive than the Audi. And it鈥檚 an enjoyment only enhanced by a fabulous cabin full of kit and class. Shame about the infotainment system though.

Top choice: 350d AMG Line

7. BMW 7 Series

This is a big bit of kit, but it鈥檚 also fun to drive so, even in this extra-long version, you might be tempted to shove the chauffeur out of the way. Not that you need either of you to park it, since it can do it remotely. The car is full of clever tech and of course the incomparable iDrive system.

Top choice: 730Ld

6. Audi A6

The A6 is a lot cheaper than the BMW 7 Series, but it has an even classier cabin that comes fully equipped from base level up. The economical 2.0-litre unit we鈥檝e chosen just adds to that sense of value for money. Do bear in mind though that a new A6 will arrive towards the end of 2017.

Top choice: 2.0 TDI Ultra SE

5. Jaguar XF

There鈥檚 maybe a question mark with cars like the Rolls-Royce or the BMW 7 Series whether you鈥檇 rather be in front or back. There鈥檚 no question here ?this is a driver鈥檚 car, luxury model or no. With impeccable handling, and that slightly different sense of British luxury, the XF is a great car for long-distance work, and in Portfolio spec you also gain reversing camera and keyless entry among other goodies.

Top choice: 2.0d 180 Prestige

4. Porsche Panamera

The second generation of the Panamera shows a car that really can devour continents, while keeping all four occupants extremely comfortable, entertained and amused. And thrilled ?whether with petrol or diesel power, the Panamera gives an object lesson in how to shrink horizons.

Top choice: Diesel

3. Mercedes E-Class

This may not be the teeth-bared driving machine that some dream of, but at this level what is often demanded is a soft, comfortable and controlled ride, while sat in a cabin of opulence, surrounded by all the latest technology, including a vast digital instrument cluster. And with the 2.0-litre engine, you鈥檙e not even paying that much relatively for such a fine experience.

Top choice: 220 d SE

2. Mercedes S-Class

The second Mercedes on the podium and it鈥檚 not a surprise to see the S-Class here. We, cough, hesitate to say so, but the ride delivered by the S-Class and the low level of noise that intrudes are both rather superior than in the Rolls-Royce, which costs about three times as much.

Top choice: 350 d L SE Line

1. BMW 5 Series

Just look at what it鈥檚 achieved so far this year ?not only the What Car? Luxury Car of the Year, but also the overall Car of the Year. Not a bad start to 2017. The new 5 Series is so advanced, so comfortable, so clever, and so good to drive that you question the need to choose any other car on this list ?and that includes the BMW鈥檚 bigger sibling, the 7 Series. A truly sophisticated winner.

Top choice: 520d SE
