It won't be one millionth as good as the ones I'll have when I go home''

Is it a new car? A speedboat? A caravan... with awning??!! Unless Marcus thinks he's been teleported onto the set of Bullseye for the afternoon, we can safely say that his individual special prize from Big Brother (coming to all housemates if they convince Rodrigo that he's meeting the REAL queen) won't be any of the items above.
But that hasn't put the window-fitter off wanting one.

Coming into the Diary Room for a chat with Big Brother, Marcus revealed that his previously promised special prize - a guitar and amp - might not hit the spot this time. In fact, he wants something else. Something bigger. Something more expensive.

"Just wondering what I deem a brilliant individual special prize, and what you do. I'm thinking a guitar and speakers might not be a brilliant prize. It won't be one millionth as good as the ones I'll have when I go home, which I made. Not that I'm ungrateful or anything like that, just putting it out there that a brand new car in gun-metal grey might be a bit more to my liking."

"How do you think your fellow housemates feel about today's task?" asked Big Brother.

Guess a car's out the question, then.
