She has to spin it over a few times before the car will stay running.  She then starts revving it with her cowgirl boots, working the gas to make the engine’s rpm’s dance up and down.  She gives a little smile to the camera in the process of revving it.  After a few minutes, she slips the boots off and revs it with her socks bunched up a bit on her feet.
This clip knocks out a few requests for socks and cowgirl boots while revving and what better way than do it while introducing a new model. 🙂
