Barrett-Jackson to Sell First-Production 2010 Ford Roush Mustang Special-edition Roush Mustang to be auctioned off for charity. Proceeds from the sale of the Mustang, which is one of only 25 will benefit the Michael Phelps Foundation. Advertisement Barrett-Jackson is a place where car collectors gather to drool, dream and if they’re wealthy enough, buy their dream vehicle. If you’ve never been to the Barrett-Jackson Auction in Scottsdale, Arizona, put that down as a bucket list event. Certainly car enthusiasts, including and especially Mustang enthusiasts, can find plenty to drool over at Barrett-Jackson. This year there’s something very special on the block for Mustang enthusiasts. I love rare and special Mustangs!
