Here is an update on "The Convincer II": after having been repainted white pearl/dark red metallic in 1979 the car was campaigned with "Convincer IV" on both sides (look at some earlier shown black and white photos).
In 1995 it was sold to a guy in Malmö who repainted it the way it looks below, with "Idunsgatans Bil" on the doors.
Now to the news: after I spoke to the owner who had it a few years ago he has apparently sold the car to Denmark. I found this pic taken at Feringe Dragway in 1997 on Facebook a couple of days ago, and a danish guy says that the body and crome on it still is flawless. I wonder if the Cragars are the ones used in N.J. in the seventies ??
Before shipping the car to Sweden they bought a hoodscoop at Motion Performance on 12/14/77, paying $69.55 tax included. I assume that is the scoop you see on the car in this pic.
