Thanks for the clues. The odometer shows, if I recall, 37K km. Frankly I don't believe it, because of the interior's looks, but it doesn't matter. Having started it, allowed it to idle for a while, watched the temperature get adequate, and then started to step gently on the gas. The needle wouldn't get passed the middle, (I think "5"). The engine sounded smooth, no smoke or anything, no hesitations, but I didn't try driving it. So that's it, I thought the needle should have gone to the top, as it goes in other cars.
