More often than not, the final iteration of vehicle within a production run turns out to be the best. It could be argued this was the case with the Mercedes-Benz W126 S-class. Making its debut in the early 1980s and lasting in production through 1991, there were many technical advancements along the way, with a facelift that streamlined the look in 1986. However, that leaves a bunch of cars from early days of a production run sitting around like unwanted step children, hence the case with this 380SEC for sale in Colorado. I much prefer the updated look and greater power from the later 560SEC, but one look over this grand coupe tells me this is no ordinary SEC, looking perfectly preserved at well over 30 years of age.
