Cars and gadgets go together like fish and chips. So much so that one intrepid retailer has hollowed out the guts of several toy cars and put a mobile phone inside them.

It's a BMW, but also a phone. Genius!

There are three cars to choose from: a Ferrari, an Audi TT and a BMW. But the talking point of each - literally - is that all three have a mobile phone slotted into the undercarriage. So instead of changing the oil or pumping in petrol, you simply have to slot in a SIM before you’re driving chatting away.

The Audi comes in white and the BMW is available in boy-racer black. Both feature 2.2in touchscreens and a 1.3-megapixel camera. There might not be much storage in the boot, but 1GB of internal memory is available and Bluetooth is included too.

The Ferrari has a windscreen-mounted camera

Each dual-band phone also supports MP3 tunes and MP4 video, while setting you back around £112 (€132/$224). But, hey, at least they’re road-tax and congestion-charge exempt.

If you’re looking for something with near-identical features, but set within a more stylish body, then the classic red Ferrari will be more up your street.

The phone has a 2.2in LCD touchscreen, supports MP3 and MP4, and has dual-band connectivity. Surprisingly, given that it’s a Ferrari, the phone is slightly cheaper than the others: £100 (€120/$200). It’s also available online in yellow too.
