Lamborghini has unveiled the world most expensive retail car, set to be released in October.

The £1.77m Sesto Elemento comes with a 5.2-litre V10 engine offering a top speed of more than 200mph, and its carbon fibre body enables it to go from 0 to 62mph in 2.5 seconds.

It is so light it doesn't meet roadworthy regulations, meaning you'll only be able to use yours on the racetrack.

But its price tag pales when compared with those seen for many classic cars in recent years. A 1936 Bugatti Type 57SC Atlantic is currently the most expensive vehicle ever sold, making around £18.4m in May 2010 at a Gooding & Company auction.

The figure is a reminder of how classic motors far exceed contemporary cars in terms of value.

But investors take note. Lamborghini is producing just 20 Sesto Elementos, almost certainly guaranteeing them "instant collectible" status. What price will one of them command in 10 years' time?
