It is amazing what a color can do to a car. You could have identical cars, one with a really desirable color and another with a not-so popular color, and have their values be dramatically different. Today’s car, a 1983 Mercedes-Benz 300TD for sale in California, is a perfect example of that. Regardless of color, the W123 300TD is no slouch in terms of desirability and people willing to do anything to keep them on the road. But paint it in a color that everyone loves and suddenly you’ll be a little shocked to see what kind of money these can bring on the open market. This 1983 painted in Labrador Blue isn’t a perfect example by any means but that is the appeal of an example like this. You can enjoy it without obsessing over every single thing that might happen to it. But seeing as this is a 300TD and it is in Labrador Blue, how high could the price be?
