First 2015 retail Mustang goes for $300K

Compared to your typical Barrett-Jackson collector car auction price, $300,000 might not seem like too much--a 1967 Corvette went for $3.8 million. But with 100 percent of the proceeds going to the Juvenile Diabetes Research Foundation, $300,000 doesn't sound too shabby.
