Trump embarked on a five-day trip to Scotland from July 25 to 29, mixing business and leisure in what the White House called a "working visit."

The president played golf at Trump Turnberry, his resort in Ayrshire, and opened a new 18-hole course at Trump International Golf Links in Aberdeenshire. He also met with UK Prime Minister Keir Starmer and European Union chief Ursula von der Leyen and announced a new trade deal with the EU.

Trump was joined by Eric and Lara Trump, Donald Trump Jr. and Bettina Anderson, and two of his grandchildren.

The black vehicle, which appeared fully enclosed in black panels and tinted windows, stood out among the regular golf carts. Media outlets began referring to the cart as "Golf Force One," a play on other presidential vehicles such as Air Force One and Marine One.

Retail prices for Polaris Ranger XP models start at $20,999, according to Polaris' website. Armor kits for Polaris Ranger XP vehicles come with a much steeper price tag.

The War Zone reported that the US General Services Administration's website lists a Polaris XP 1000 Ranger UTV armor kit manufactured by Scaletta Armoring for $188,922.92 that appears similar to the one accompanying Trump.

A Polaris spokesperson told The War Zone that the vehicle was manufactured by Polaris, but customized elsewhere.

Representatives for Polaris and Scaletta Armoring did not immediately respond to a request for comment from Business Insider.

Jim McGuffey, an expert witness and global security consultant certified by ASIS International, told BI that it's safe to assume that the vehicle has some protective value, such as armor and bulletproof glass.

"It is armored, or it's material that looks like it's armored, and I would go with it's armored," he said. "To what level? I have no idea, nor do I think anybody else would by just looking at it."

"The US Secret Service employs a variety of tools and resources to safeguard our protectees," a Secret Service spokesperson told BI. "This vehicle is part of our presidential fleet of specialty vehicles. In order to maintain operational security, the Secret Service does not discuss the specific means and methods used to conduct our protective operations."

Other golf carts, such as one driven by Eric Trump, featured signs reading "Honored Guest," designating them for use by VIPs.

Golf carts have often been the vehicle of choice for presidents visiting the 180-acre presidential retreat located in Maryland's Catoctin Mountains.
