A luxury car care company in London is now offering just the thing to spread all over your million-dollar automobile: car wax that costs GBP24,000 (US$37,070). The folks at Brough and Howarth claim that their Definitive Wax Marble is the world’s most expensive car wax, and one would assume they’re probably right. Given that there’s currently only one pot of the substance in existence, it’s also a safe bet that it’s the rarest.

The product contains refined natural fruit oils, locally sourced beeswax, and imported carnauba wax from northern Brazil. It comes in a marble cube, which we would hope is presented to the purchaser by Angelina Jolie. There’s no word on how much wax comes in one cube, or how many applications it’s good for.

Of course, people buying Definitive Wax Marble aren’t going to be applying it themselves, so they’ll need to open their gold-plated wallets a little wider yet. The automotive treatments at Brough and Howarth range from GBP325 (US$502) up to the connoisseur package, which costs GBP65 (US$100) an hour, and takes a minimum of 120 hours – a total of at least GBP7,800 (US$12,048).

We’re waiting to hear back from the company as to whether or not each customer is required to buy their own container, or if the “one pot in existence” is being used on multiple clients’ cars.
