Impreza WR1 verification

[SLIDER]

Hi there. I bought a Impreza wrx sti wr1 3yrs ago. There are a few things I'm finding out that makes me think it’s a lookalike, not the real deal. Like no plate just below the cigarette lighter saying WR1 2003 winners Petter Solberg and his signature on the plate. Also no Wr1 gear knob and no WR1 tax disc holder. Can someone please tell me how to check this out. Thanks stewart

To be sure I would contact Subaru for some for of proof of authenticity
