we bought the car new in feb. 2000. I haven't done too much to it other than changing the engine oil and trans. oil. It has been a wonderful car that both my wife and I love and has been very trouble free, so there hasn't been a need to do a lot of looking under the hood so far.
I was surprised to say the least to see green. I wonder if there are any other 2000 and up owners that have noticed the same thing.
