A one-off V8-powered Aston Martin Cygnet has come up for sale. The factory-built custom has a 4.7-liter engine from a Vantage S. In 2018 the Super Cygnet made its debut at the Goodwood FoS. In the late 2000s Aston Martin’s then-boss Uli Betz greenlighted a wacky plan to badge-engineer the Toyota IQ city car to create an Aston-branded urban runaround.

When first announced in 2011, the Aston Martin Cygnet piqued interest globally: a tiny sub 845kg (curb weight) hatchback with Aston mechanical gubbins. Where do I sign? Instead, the world received an Aston Martin-attired Toyota IQ.

Listed via Aston Martin seller Nicholas Mee in the United Kingdom, the price is marked “POA,” or price on application. The one-off Super Cygnet has 2,893 miles on it, all courtesy of the original buyer who commissioned it.

It's done 2,900 miles. We dare you to drive it more. A few years ago, Aston Martin proved that you can do just about anything if the price is right. We have no idea how much the owner of the world's only V-8-powered Aston Martin Cygnet originally paid for this wild creation.

Based on a Toyota iQ, the Aston Martin Cygnet was a short-lived luxury city car that failed to sell. This one-off swaps the tiny engine for a huge V8.
