I don't think it's wide enuff to be a "Z".....I'm think a "LT5" transplant into a convert if even that....could be just a pic of the engine...too many things don't add up..initial registration 1/90...(it doesn't have a '90 front to it)...Auto...Black Rose metalic("92 was the first year)....the VIN # would interesting to know....sounds kinda like a scam to me.
