Turnpike Red that's a colour I haven't seen before, also Berger paint code, not Dulux, I have only come across a few Berger painted cars mostly HZ's and the odd fleet HQ. Also the Body plate is the old style without the driveline info at the bottom.

Back in the 70's those K20's would have been able tow anything caravan or boat wise that was on sale, didn't they have a 292 6cyl in them originally?
