About a month ago I featured a 1997 SL320 40th Anniversary Edition. Today’s car is also a 40th Anniversary Edition — although a SL500 and not a SL320. With the smaller straight-six production being limited to 250 models, the V8 had twice that number (despite what the sellers ad says) with 500. The SL500 was only produced in Crimson Red Metallic with “Exquisite” parchment leather, some fancy floormats and EVO II wheels. Seeing as these don’t come up for sale often, let’s take a look at this R129 outside of Boston.
