Who modified this car, and what name was it given?
Any chance it's a BMW 3-series by Baur in Stuttgart?
LOCKED for AlexFrance
It is a BMW 3-series by Baur. To earn your point, tell us what name was given to this particular model?
It is called the 'Baur-Kohl-coupé'.
Good enough.
One point awarded to AlexFrance for the correct answer.
It is named after the Autohaus Kohl, a large BMW dealer in Aachen, Germany, who commissioned four of these coupes to be built by Baur based on the Baur TC convertibles.
