I went to see this car, the wheels i did notice but I also noticed the location of the SRT6 logo its on the far right barely under the E, when most SRT6s have it under the R & E (correct?) also the engine cap is not the one of an SRT it has the shield looking one used on the regular base models.

I walked away this car must have been damaged from the rear and front and given a regular or maybe limited engine but kept the SRT6 body an selling it as such.
