Time To Ditch The Aston, Will. Kate's Pregnant!

1. Jaguar XF Sportbrake

The ultimate family motor fit for Royal blood? It's certainly got bags of British pedigree to keep our Queenie quiet in the back and proves an effective way to ship the family in class and comfort. Unlike the saloon line-up, you only get the option of a 2.2D unit with two power flavours (163 or 200bhp) plus a hotter 3.0-litre oil-burner with either 240 or 275bhp. We think William would prefer an XFR-S version, however. Next...

2. Range Rover Vogue

Nothing shouts "Ra Ra Ra" quite like a Range Rover. And while there are three spec levels to choose from - Vogue, Vogue SE and Autobiography - it'd be the entry-level £71k Vogue, we think Will and Kate would use to waft little Tyson (odds on 10-1) to private nursery and back in. The 3.0-litre V6 is good for 130mph and the Vogue's interior comes caked in leather. Decent.

3. Audi SQ5

Ever wondered why, nine times out of 10, you'll see one of the Royals cruising around in an Audi? The German brand's 60 per cent discount to them might have something to do with it. (Might also explain why Audi's head of PR was invited to THE wedding, too!) For that reason, why not get a hot SQ5, Willy? It's got plenty of juice (309bhp from its 3.0 twin-turbodiesel) for trips to Balmoral Castle and for those late-night shopping sessions when Tyson's out of nappies. Oh right, you probably have 'people' for that, don't you...

4. Aston Martin Rapide

It's time to hang up the driving gloves and put the Aston DB5 on Gumtree, buddy. But fear not. You can slip into a much more family friendly Aston with all the badge snobbery you could ever hope for. Prices kick off at £150k for one of these 188mph monsters, but there's a decent-sized boot, four sculpted doors and a bassy soundtrack to sooth the little 'un to sleep.

5. Skoda Yeti

Perhaps one for Kate, the Skoda Yeti is flame-proof, "tougher on the inside than the Fire Brigade" and the perfect motoring tool to land a helicopter on top of (William is an RAF chopper pilot, after all). Our money would go on the 2.0TDI 4x4 model with a 6spd DSG 'box. It's economical, rugged, comes with leather and enough space for 2 kids, should Kate feel the need to pop two out at once...

(Odds on twins named Tyson and Chanel are 22-1, by the way...)
