German Cars For Sale Blog turns seven years old this week. Thanks to all our fans who have made this website possible over the years! To kick off our anniversary week a little bit early, we’ll take a look at this 40th Anniversary Edition SL500 for sale in California. The R129 SL is in a sweet spot for collectors right now, with R107 prices trending upwards and the R230 SL being a bit too new to be considered a classic. There were a number of special edition R129s over the years, but this edition with its Evo wheels and Designo paintwork is rather stunning. With just over 14,000 miles on the odometer, this is one for the serious collector.
