For those of us who have problems scraping enough money together for a week away in Tenerife, turning down the chance to get our name down for a chance to buy Lamborghini's new concept car, the Sesto Elemento, is quite easy.
Even though there will be only 20 built, and it can hit 62mph in under 2.5 seconds utilising its 5.2 litre V10 engine and carbon fibre chassis and body that gives it a total weight of under a tonne, the price tag of £1.77 million may just be enough to put us off - unless you really want to own the most expensive car in the world*.
Well, that and the fact that its design is so extreme that it actually isn't road legal anywhere in the world. So you'd need a nearby private racing track to take it for a very quick spin at a top speed of 200mph.
If you're still interested, you'll have plenty of time to save up for it. It's not actually been built yet, the concept having been unveiled at last year's Paris Motor Show, although Lamborghini have now decided to go ahead with production.
That'll be some big old piggy bank you'll need then!
And if that's a little out of your price range, how about one of these?
Bugati Veyron. 0-60mph in 2.5 seconds; 267mph top speed and it is street legal. The cost? A snip at around £1.05 million.
Lamboorghini Reventon. 0-60 in 3.3 seconds and a top speed of 211mph. Only 20 built (is there some sort of Lamborghini pattern here?) and sleek, beautiful and only £985,000.
McLaren F1. Once top of the pile back in 1994 with a top speed of 240mph, and a 0=60 of 3.2 seconds. Relegated now to 4th in the list of 'readily available' expensive cars at £597,000, it is still considered one of the top performers in the world of the supercar.
Ferrari Enzo. When built these cost around £413,000 and 400 were made available and snapped up. It's probably the best known of all supercars and you'd probably recognise it as it sped past you at 217mph. Available now at auctions for around $1 million.
There are others in the same sort of price bracket from the likes of Mercedes Benz and Porsche as well as lesser recognised manufacturers like Saleen, Pagani and Koenigsegg, but for now it is Lamborghini sitting proudly at the top of the table, waiting to e built as well as for 20 people to open their bulging wallets to pay for the luxury of being able to say "I own the world's most expensive car*!"
*The title of the world's most expensive car actually belongs to a 1931 Bugati Royale Kellner Coupe that was sold for $8.7 million in 1987, but if you want the world's most expensive NEW car, you'll be OK with the Sesto Elemento.
