I am very curious about the colors you mention. I thought it was always straw yellow. Have they changed to green and orange?

I think I read that write-up a while back, just wasn't sure how much has changed from w202 to w203. Probably not much but you never know.
I asked the parts dept. guy at MB of San Diego about the green coolant. He said that the coolant used at the factory in germany is green and supposedly good for 100,000 miles. The orange stuff is the right/best stuff to use if you reside in N. America and need to replace coolant.
The factory green coolant isn't available in N. America. The coolant I purchased from the dealership is orange.
I would be more skeptical about the "factory green" coolant, except that the car was dealer owned and serviced prior to me taking ownership. I doubt they'd use non mfg. spec fluids.
