Decoding spec of potential purchases

[Bushido]

Hi again all,
Is there an available resource for checking spec / build details of potential purchases please? I seem to recall that Ian is often good enough to help people along here and that I have seen the folks at a8 parts disappear to their computer screens and come back with info?
I only ask as , I’m realising just how generic and inaccurate many of the populated spec sheets on autotrader etc are. I accept they just wok down a tick list , but

thanks as always, Paul
