In that case it could be anything, ...undercar neons, front strobes behind the grill, gate/garage door opener, machine guns, oils slick etc etc.
Okay the last two suggestions were a bit tongue in cheek, but could be any of the rest.
An ejector seat would be good (but there's no sunroof either so maybe not )
No can seem to find anything it currently does so whatever it was is gone now.
Cheers for the input
