Inside King Charles III's $15,150,000 car collection which includes special details that reflect his personality

King Charles III’s $15,150,000 car collection is exactly what you’d expect for a monarch, with special details that reflect his personality.

Ahead of King Charles’ 77th birthday on November 14, Marshall Motor Group revealed the value of his enviable car line-up.

It included everything from Rolls-Royces to Aston Martins.

And as you might imagine, these cars would go for a lot more at auction than their market price.

Taking a look inside King Charles III’s $15 million car collection

King Charles’s car collection is a mix of personal vehicles owned by him personally alongside state vehicles held by the Crown.

“While state vehicles aren’t personally owned by the King, they remain an essential part of his public image,” Ben Welham, the motoring expert at Marshall Motor Group, said.

“These cars represent royal tradition and ceremony reserved for state occasions and public engagements. Many of them can’t be bought ‘off the shelf.’

“They’re bespoke and steeped in royal history, which elevates their value far beyond standard market rates.”

So, which cars have a special place in His Majesty’s personal line-up?

Rolls-Royce cars feature repeatedly – a 1950 Rolls-Royce Phantom IV ($3.92 million), a 1962 Rolls-Royce Phantom V ($3.92 million), and a 1977 Rolls-Royce Phantom V1 ($1.71 million).

And let’s not forget the $460k Rolls-Royce Cullinan Series II he was gifted back in 2023 by the King of Bahrain.

There’s also a Lotus Eletre (estimated to be $184,000), a Jaguar I-PACE (estimated at $92,000), an Audi e-tron (approx $65,000), and a BMW i7 (around $217,000).

That’s not forgetting two Bentley State Limousines, worth $1.84 million each.

And that’s not forgetting the Aston Martin DB6 Volante Series II, gifted to him by his late mother, Queen Elizabeth II, which is worth upwards of $2.63 million.

There’s also the vintage car collection at Sandringham Palace, which has been part of the royal household for decades.

Some of these cars are seriously old, including an electric Citroën C4 from the 1920s that was used by the Queen and Princess Margaret as children.

What does this collection say about the monarch?

As you might expect, the cars in this collection would fetch a lot more at auction than their market value, thanks to their royal ties.

Remember when the late Queen’s Range Rover went up for auction?

That car ended up going for $230,000, more than double the anticipated sale price.

But it’s just not the extra value that makes the cars in King Charles’ possession special.

This collection puts a spotlight on his commitment to sustainable motoring – an interest held long before EVs became mainstream.

“Charles has been ahead of the curve on green motoring since long before it became fashionable,” Welham said.

“His Aston Martin DB6 famously runs on surplus wine and cheese whey, a biofuel conversion that seemed eccentric 20 years ago but now looks very innovative.”

Of course, it’s not just in the UK that royals get to enjoy swanky car collections.

The Sultan of Brunei has approximately 2,391 vehicles at his disposal.

But some royals have a more low-key approach to transportation – Prince William opts to use an electric scooter for his commute to Windsor Castle.
