No that's not the car. I have seen a pic MkIV that was doctored to look like a MkII. It had the '85 style rear spoilers that looked very close to the orginals retrofitted to a MkIV. It also had a SUPRA sticker on the hatch that had the same size/fonts as '84+. There were also some other things that were done to that car that reflected the sprit of the MkII.
There was once a thread about this car on SF being the ugliest MkIV ever or something. Something about mixing the MkIV and MkII doess't seem right IMHO. I'll see if I can locate that pic.
I saw an IS 300 with a Spoiler at the top of the window the other day, and I swear, it looked like someone had take one off of a Mk II and shrunk it. It was maybe 4" wide, and the "pillars" on the ends that connected it to the body were about 3" high.. was very cool, and the first I had ever seen..
