274 is indeed a 190SL color and was not offered for 280SLs. However, I am interested to find out if the color was used for other MBZ models in 1970. My original color is 396 (Medium Blue Metallic), but the car was painted a color like 274 (think celery) in the 1970s. I'm considering an engine out paint job and debating whether we put the car back to its original color (better for value) or keep it light green (our preference). We don't have any plans to sell the car and we drive it regularly, so we are leaning towards keeping it light green but using a proper MBZ color (274). It would be ideal if this color was offered in 1970. Thoughts?
