Impressive, but she isn't the one in the Barracuda episode preview shown above. The current one has longer, darker hair. Then again, I could probably count all the Overhauling episodes I've seen on one hand so no doubt I've missed a number of women crew members.
I don't dispute that there are women out there that know their stuff, can work on cars, and outdrive a majority of guys. But there seems to be a trend of putting women on the cars shows where they are project coordinators, or story accomplices, or they install some gaskets or bolt down a carb. Not exactly technical stuff.
