But very few people know about this car.

It's the S 63 Cooper, and it's kind of forgotten amongst the hordes of Portia's and Lamborghinis and Bentleys that operate in that price range.

But I'm telling you, this might be one of the best cars on sale because it's not cheap.

It's well over £100,000 with options.

I don't admit how much this one is, but it's the most beautiful product.

Everything in here is of the very best quality is in a shortened S class chassis with air suspension on their familiar five and 1/2 litre twin turbo charged V eight, which has now been replaced by the four litre twin turbo charged V eight from the E 63.

It's confusing, I know, but I'm telling you, I don't know of a car that better combine speed and comfort, and I've driven every car that's supposed to do it.

So how's Mercedes made such a brilliant car and failed to tell everyone about it?

Now, this is quite an old car.

In fact, it feels like a used car of you now.

But the engine is the old school twin turbo charged V 85.5 liters, 585 horsepower and 664 foot pounds of torque into Talk Monster.

The gearbox is a bit slower than it now is.

But I tell you, this is the power train of choice for this type of car on with shorter wheelbase that an S class, it's much, much more agile machine.

I can't tell you how well balance is between comfort and speed on UK roads.

This is the most impressive GG car I've ever driven.

I'll tell you what made it so good.

It's just a level of comfort, quietness and general feeling of not actually being in a car.

But that demonstrates quite a big problem when you're making car video because there's no way of me saying Listen to how quiet it is.

Well, I'll do it now.

That's my isn't it quiet face.

I'll now do my ride.

Comfort face.

I mean, the right comfort is freakish.

I've never driven a car like it.

You see stuff you're I say, Oh, that's a bump.

When you go over it, nothing happens.

You get a little noise like that and nothing happens.

The cumulative effect off that silence on that ride comfort is that you normally get out after a three hour journey fresher than when you started.

That doesn't happen in an Audi A eight.

That doesn't happen in a BMW seven series.

It only happens in this car when you think about it.

When you're stressed, you got lots to do.

That's an incredible trick.

But alongside the freakish levels of comfort on lack of fatigue, this car, it's riddled with toys.

In fact, there's so much fun to be had poking around.

The details of this car doesn't have to stop and show you Theo s 63 Coop.

It's all about the details.

It's often accused of looking just like a slightly bigger C class Aurica Scooby.

But it doesn't look at these lights here.

Those are individual early days and above the mark Swarovski crystals.

This thing reads the road ahead.

That's why it says led intelligent like system.

Don't get that on the C class.

Come around the side here.

Now, the next time you see one of these on the road.

If you do, because I quite red look at that line down the side.

It's sort of suede on.

It starts in front of the front.

We're on it comes away back, one line, uninterrupted all the way back behind the rear wheel.

And it gives this lovely tension down the side of the car thing.

It's fantastic.

Doesn't have fallen arches, but it still looks really wide and punching the boot lid.

Has this doc tell here that's built into the metal work and that does actually spoiler and producers reduces lift.

Okay, but enough is this extra crease here.

So the line follows off the boot lid on the rear panel here.

This record a panel just has this little hint.

Have a crease here, just a tape of that line in.

It's that level of detail that I find fascinating about this car because people think it's just a big Mercedes coupe.

It isn't.

It's totally separate toe all the rest of the range.

That's why the little elements in the rear heated screen are so small they're invisible.

They're not on a normal Mercedes.

This is a reminder of the fact that Mercedes Benz has always been a maker off the finest cars in the world, and they can be quite expensive now.

Any great luxury car cabin should be full of toys and things to play with, and this is one of the best.

I think of all the features of enjoyed during 17,000 miles of living with this car.

This is my favorite.

The driver can control the passenger seat effect to be It's like being in a D B five pretending you're James Bond.

So you press left and you can just move your passenger backwards.

Forwards up, down.

Look, I'll just say to the ceiling now.

If you've got little people Children, there's nothing better than winding them up by just sending them up and down around.

You can also control their heated seat, and he control there.

Ask off this thing has the fan heater that comes into your neck like it does it in that cell so effectively you can warm and cool the other person in the car in the front with you as much as you like.

I love that it's totally unnecessary, but it's just great.

Great theater deceits themselves but they couldn't be better.

Has moved out of the way for the camera about that Christmas.

Just demonstrating again.

Brilliant!

Of the S class.

Cooper.

The seat itself is so adjustable, I'll leave it to kneel to show you what happens on the screen.

But you can have everything from active bolsters.

Passive.

Baltar's move.

Everything is in, out, up, down, around, about.

It is truly remarkable.

If you can't get comfortable in this car, you can take comfort in any car.

The only problem is if you are short ass like me.

By the time you find the right driving position, some of the dolls become obscured.

In fact, they're pretty much cut off by the top of the steering wheel.

But that doesn't matter because there's a head up display that I can read on the screen.

So that's fine.

I just use the H u D.

There are two main screens here.

Like the reason An s class I can't really fault whatever information it is clear, precise, not too fancy, but just enough there to to make me feel I mean something very expensive.

The lever.

Look at the level this baseball glove thick, dizzy neo brown leather.

It's fantastic.

Other details.

I love the Swarovski crystals almost had some Russky, right?

I'm not gonna try again.

There's one here.

Okay, there's a crystal that sits on your copy there when you open it, which I find it's a bit not really, isn't it?

I'm not that into crystals.

The center armrest thing here is brilliant.

This is classic Mercedes Benz, brilliant because it opens both sides, but it does so the same way.

How's that even possible when there's no visible hinge?

I still mean snake oil, isn't it?

It's incredible.

These open here to give you a cop holed up.

The other thing I love is that you fold that down and that's where you get your CD out.

But it doesn't mean that you can't drink a drink and take a CD out at the same time, which is an enormous failure from his lady friends.

And I have a look at that for the face lift.

What else have we got?

All your buttons down here for your chassis controls for your gearbox to be sport, manual or comfort.

But most important of all is a little sign here from the Tweeter.

All the speaker covers are metal.

There's one up there for the surround sound.

There's a few around here.

The bro messed.

I find this thing is the best hi fi I've ever heard in the car there, sub standard foot wells, and then the top end comes seamlessly out above the scuttle.

Their it sounds incredible.

It's such a compromised environment, and I know that there are companies like Name that I love for home high five, making car heist for other car manufactures and making lots of noise about it.

Mercedes doesn't make any noise any PR Lloyd's about the high find this castle, but it is unquestionably the best I've ever heard in a car.

So the combination of silence ride, comfort and sitting like urine, a live music auditorium makes for the most compelling long distance vehicle I've ever ever bean.

There's enough room for two little people in the back.

I wouldn't say it's a genuine full four seater, which is remarkable given it casts a shadow that of a five.

Siri's a bit more, but you have the seats a bit further forward.

You can get to grown ups in the back, but not really long ones.

You won't want to long journeys with the brute.

A decent size on the rear.

Seats are heated as well.

Bum Woman's are critical, I think, Um, as you can tell, I'm a bit enthusiastic about it.

I love it.

I've lived with this thing for a long time, but I think it's amazing.

Anyhow, enough of the static review.

Let's head back out onto the road.

The next S 63 Cooper trick is size shrinking.

This thing is a big, big, heavy old boat, but once you start threading it down the road, you wouldn't believe how smaller can fill.

It never feels a smaller, the three Siri's, but you can really pound it down a road.

And, of course, that air suspension, its compliance helps you when the service gets choppy.

Mid corner bumps, not a problem whatsoever.

You just keep pushing.

It keeps building speed, and you could actually enjoy driving it fast.

I mean that you really can't.

In fact, it's so good to drive fast.

You can even do this with it.

Something so naughty about big fast cars being driven in a city fashion.

So let me just be quiet for a minute and let you watch a well over two ton Mercedes Benz sliding around a wet circuit somewhere in well, to me, it just looks magnificent.

Just the best guy, no one ever just competing.
