I write a lot about Mercedes-Benz and their monetary values. The overwhelming majority of the time their values are depreciating or, at best, holding steady. Every once in a blue moon I come across a car which is actually appreciating in value. Today’s featured car is not only appreciating, but is one of the hottest models in the substantial Mercedes-Benz catalog you can buy at the moment. That car is the 190SL. Produced from 1955 to 1963, the 190SL was the baby bother of the now seven-figure 300SL. Although similarly styled, the 190SL was much different mechanically than the 300SL with a carbureted four-cylinder and built on a shorted saloon chassis as opposed to a tubular space-frame like the 300SL. Because of this, 190SL values stayed relatively flat and didn’t have great demand outside of a few particularly outstanding examples. However, now that the 300SL have reached a point where they are so valuable that even putting miles on them is frowned upon by collectors, the baby brother 190SL isn’t so “baby” anymore in terms of value and collectibility. Today’s 190SL for sale in Ohio is right in that sweet spot for a classic car that can be enjoyed.
