what is the most expensive car in the world 2023

For 2023, the priciest new car is the Rolls‑Royce Boat Tail, a coachbuilt special costing about AUD 40–45 million depending on exchange rates.

Overall, the title belongs to a 1955 Mercedes‑Benz 300 SLR “Uhlenhaut” Coupé, auctioned in 2022 for €135 million—roughly AUD 200+ million—and still unbeaten through 2023. In short: new money buys a picnic set; old money buys history with doors. Prices wobble with FX and fees, but those are the bragging-rights ballparks. Try not to drop the keys.
