As of my final information replace in January 2022, there isn’t any particular details about a Mercedes C300 Cabriolet with the designation “w112.” Usually, the “w” adopted by a quantity is used to indicate the chassis code for Mercedes-Benz automobiles. The W112 chassis code, nevertheless, is traditionally related to the Mercedes-Benz 300SE sedan from the Sixties.
It is potential that there have been updates or new fashions launched since then. To get probably the most correct and present details about a Mercedes C300 Cabriolet with the particular chassis code “w112,” I like to recommend checking with the official Mercedes-Benz web site, contacting a neighborhood Mercedes-Benz dealership, or referring to the most recent automotive information sources for the latest particulars on Mercedes-Benz fashions and their specs.
