Yeah Recaros have the name embossed in the back (about the middle of your back unless you're a midget). IIRC all the Colour Concepts came with Recaros, and the leather you could specify on the other cars (like the Highline and VR6) were either tan, black or dark purple and have nothing written on them.
As for value - Colour concept interiors will go for between £350 and £700 for a good one, maybe 'standard' VW ones a bit cheaper.
And hook the heaters up, on a cold day they're worth exactly one testicle and one arm.
