On October 31, this steam beauty under the hammer at Bonhams in London, unfortunately, I sit myself in the car on the road just to London that day, so I do not buy it.
It is estimated that it will fetch at least 350,000: - £, which corresponds well a bit over 4 million ....
It is a Gardner Serpollet manufactured in France in 1904 or 1905. Check this link https://www.bonhams.com/video/17679/
I am a self-taught steam car engineer whose interest is in the renovation, repairs and manufacturing of steam car parts....
