Jersey racing driver James Walker has admitted his dream of competing in Formula One is now over.
Walker said potential world champions are failing to break into the sport because it is too expensive.
He told BBC Radio Jersey: "I'm 100% sure there will be people who've approached F1 and been side-stepped who would've won world championships."
The 28-year-old was close to joining F1 in 2009 but failed to get enough sponsorship.
He added: "You do all the hard work and you get to the point of being offered the drive.
"As drivers are finding now, at Virgin to be at the back of the grid for the year was £6m, which is an incredible amount of money."
He made the switch from single-seater racing to sports-cars a year ago and has described his two victories in Le Mans Series as "very special".
Along with team-mate Rob Bell, Walker finished second overall in their class to qualify for the world famous Le Mans 24 hour race.
And although he has not yet re-signed for 2012 he is hoping to continue with JMW.
Walker said: "Looking back now I thought that if you told me my Formula One dream was over that would be a negative thing, but the year I've had it's been the best thing that's ever happened to me.
"At the moment we're just putting everything together to hopefully return to the Le Mans series with team JMW.
"It would be nice to stay in the Ferrari as well, this year was a great experience."
