I see the VW K70 mentioned. I bought one in 87 after first owner. About 40,000 miles. A very odd car - super smooth engine - nice but bland cabin...but very odd to drive with strange seats which felt like sitting on a spacehopper. Sold it after a year. Can see why it was not a success
You might remember there was no space beside the clutch pedal to rest your left foot.
Definitely not a sales success in Britain - only 800 RHD cars ever built. I had a '73 90hp "L" between 1989 and 1992. The only other one I saw at that time was a blue 1971 LHD car brought in from Sweden and re-registered on a "K" plate.
I had an RO80 too. Again a bit bland - had a Ford V4. Not a car I fell in love with either
Shame you didn't get to try one with a proper rotary in it! Better with a Mazda.
