Hello Lutz!
Thanks for the comment. The gauge symbols are later, "normal ones". One thing is interesting..doors inside are one colour-brown, many brochures show them them two colour, how about yours? Yes, i know this red car, i spoke with the owner last year. This is one of the three "early ones" here, situation or condition of the third one is unknown to me. Number of the chassis of this red car is somewhat smaller than mine (made earlier). The owner said, that he doesn´t have to sell the car, but if someone is seriously interesting he will sell it. I don´t know what the situation is today, maybe it is still there. What is the chassis number of your car, it´s made quite early?
I was just today replacing heatexchangers, old ones were quite bad and i was lucky to find new original ones for 100 euros earlier. Only three things

made me work little extra- get the exhaust nuts open, get those metal exhaust sealings away and maybe the hardest part..find new 7 mm nuts, but that´s another story.
Is your car original or?
Gute nacht, Rade
