I didn't even know there was a KARR from that TV series. Very cool build. I like it in black and white. Interior color looks great too. I sure learned a lot about the vehicles from that TV show thanks to your build series.
Would this be the 3.peaks nippers you're utilizing? I found these on Amazon.

Very nice. Excellent color and very well done interior. Sometimes one wonders why such an impressive vehicle never went in to production. I realize it was just a concept, but still.
