Hi all and thanks for the replies.

I bought the car. I had a EsCos owner with me and he looked through it and he test-drove it. So I only tried it when I collected the car

It's quite fine all in all, and what he thought was something and a light in the dashboard was the brakesystem making vacuum or similar.
It's in the shop now to have the timing belt, water pump and more changed.

It has other flaws and dinks but I'm VERY happy with it. A wish come true after almost 20 years

The picture is from the sale.
