This last clip starts out on the rear of the old Cadillac as Britney gets it fired up and tons of thick, white smoke comes out the tailpipe! She gives it some revs until it clears out, which takes a little bit. You can see the big black spot on the driveway the girls left from their little ‘show’ they gave ole Ralphie today.
The view changes to inside the car of Jane filming Britney who is doing some ginger revving of the Cadillac. She’s just trying to get it cleared out some while Jane encourages her to lean out and look back at the exhaust while revving.
Jane then swaps with Britney and does some leaning out hard revving while we view from outside and inside the car.
