Is that right – £5,100 for a set of black curtains in a Bentley Mulsanne? There’s something rather funereal about the gentle glide of the electric motor that draws them together and cocoons the back seat in darkness.

And just what are they for? I suppose that if you are an Arab sheikh, who doesn’t want to wear sunglasses to avoid publicity, they could be quite useful. Or maybe they’re so the chauffeur can have a kip in the back while waiting for his passenger…

Personally, I think heavy tint glass might be more effective, and cheaper. Although that could be deemed rather uncool these days, as even Ford and Skoda owners can black out their windows for maximum bling appeal.

Still, there’s no finer place to be than in the back seat of a Mulsanne. It’s like flying first class, with deep pile Wilton overmats (an extra £1,060) and the Entertainment Pack (£21,145).

What’s that? Well, it turns the Bentley into a Wi-fi hotspot and adds picnic tables – crafted from solid metal, fine veneer and leather – that are designed to accommodate an iPad and wireless keyboard.

Add twin eight-inch LCD screens incorporated into the backs of the front headrests, a 20 GB hard drive and DVD player, plus a pair of Bluetooth headphones and a remote control, and you can see why this is the only way to fly…
