Somethings not adding up then, hence why i've asked on here.
Either it's got more done to it, which means when I pick it up I'm not insured, or it's not putting out what they are claiming it to be (more likely!).
I asked them to email the spec and all the mods so I can declare to the insurance for a quote, they forwarded me a sheet with all the specs etc.
For modifications there was "PERFORMANCE UPGRADE 330BHP, 18" GOLD GT1 ALLOY WHEELS, STI FRONT LIP SPOILER, MESH GRILLE CONVERSION"
not sure about this one now to be honest!
