Jeremy Clarkson has revealed he's spent thousands of pounds consulting lawyers while trying to come up with a name for his new Amazon Prime series and he’s still no closer to finding a title. Writing in his column for the Sunday Times, Clarkson said most of his suggestions have been ruled out by legal advisors who say they have already been trademarked.

“I spend at least six hours a day in my office — which is insured and smoke-free and resplendent with potted plants — sucking creatively on a corporate Biro as I wait for the daily 3pm ‘Anything yet?’ phone call from Amazon in Los Angeles,” he wrote.

“Every morning, I’d make a £7,000 call to the lawyer with an idea, and every afternoon I’d get a £7,000 reply saying the name was already in use by someone in New Zealand or France or Ukraine. Prime Torque. Autonation. Skid Mark. Everything was a no-no.”

One idea Clarkson wanted to go with was calling the show ‘Gear Knobs’, but he was eventually advised to stay away from anything with ‘gear’ in the title. “We thought it was amusing and hurriedly we put in another £7,000 call to the lawyer,” he said.

“She said the trademark was available, but it would be an unwise idea, owing to the laws surrounding intellectual property. In short, the BBC not only owns the rights to the Stig and the Star in a Reasonably Priced Car and the Cool Wall, but also to any name that is remotely similar to Top Gear.”

“We tried explaining there’s a show called Fifth Gear that doesn’t belong to the BBC but it was no good. Arguing with a lawyer costs more money than we had, so we hurriedly put the phone down and went back to the drawing board.”

“We need a name that isn’t in use by any business anywhere in the world and doesn’t even sound or look like any name that’s in use by any business anywhere in the world,” he added. “And it can’t even be a minor play on the words Top or Gear. Oh, and it had to be a name that was liked by me, our producer, Hammond, Eeyore and a billionaire in Seattle.”
