US President’s Cadillac for sale… but not the one you think

US President Joe Biden's custom-ordered 2018 Cadillac ATS-V performance sedan is up for auction.

While the US President is chauffeured in a Cadillac limousine – nicknamed 'The Beast', but codenamed 'Stagecoach' by the Secret Service – this Cadillac ATS-V was leased by Mr Biden following his stint as Vice President during the Obama Administration, and after President Donald Trump was sworn into the top job in 2017.

Specially ordered by the then-former Vice President, the Cadillac ATS-V is finished in Black Raven paint with a unique Kona Brown leather interior.

Introduced as a competitor to the BMW M3 and Mercedes-AMG C63 in 2016, the ATS-V has a 3.6-litre twin-turbo V6 sending 346kW and 603Nm to the rear wheels through an eight-speed automatic transmission.

The US Secret Service does not permit Presidents and Vice Presidents to drive on public roads during their terms, or up to six months after they leave office.

While he's been an advocate of electric vehicles during his time in office, the 81-year-old President is known to be a car enthusiast.

President Biden owns a classic Chevrolet Corvette convertible, which was a wedding gift from his father – the owner of a Chevrolet dealership – in August 1967.

While he was Vice President, he appeared on an episode of Jay Leno's Garage, performing a burnout in his Corvette on a closed course.

It appears the Kona Brown interior of his Cadillac ATS-V – ordered specifically by the President – may have been to match the brown leather interior of his Corvette.

The news comes just weeks after former President Donald Trump's Lamborghini Diablo VT Roadster set a new price record at auction, selling for $US1.1 million ($AU1.67 million).

The 2018 Cadillac ATS-V is being auctioned on US website Cars & Bids, with bidding at $US30,000 ($AU46,000) at the time of writing. You can view the listing on Cars & Bids by clicking here.
