The Mercedes-Benz R129, in my opinion, is in that limbo stage where a it’s not fully a considered a classic yet, but it’s starting to be eyed up as a future collectible for the right models. In typical SL fashion, the chassis ran a staggering 12 years from 1990-2002 which saw many face lifts and engine updates. Seeing as there was a giant difference in technology between 1990 and 2002, the first R129 that rolled off the line and is a lot different than the last R129 that did. Today’s SL for sale in California is towards the end of the production cycle and takes advantage of almost all Mercedes had to offer at the time.
