hahaha.. yeah, I would go e38 as well.. but its because I have one.
If you are a DIY, there is more knowledge out there in the forums for repair work on the E39 than on the newer 5s. Plus there are more electronics (both good and bad) on the newer 5s. Do you like the body styles equally? Both E39s and E38s are very well priced at the moment..
