W108 CNG Conversion: 1970 Mercedes-Benz 280SE

The Paul Bracq styled W108 generation Mercedes-Benz S-Class is (in my humble opinion) one of the better ways to get into a vintage sedan for a semi-daily driver. The performance is acceptable, ride is comfortable, build quality is exemplary, but most importantly — drive one and you’ll look like a boss. Today’s W108 has a 6-cylinder gasoline engine that has been converted to run on CNG (compressed natural gas) and some rust along the doors that needs to be investigated. I wonder if you can get those California CNG carpool lane stickers for this thing? Find this 1970 Mercedes-Benz 280SE offered for $5,900 in Pasadena, CA via craigslist.
