Sorry if this is a bit late. I purchased a 2000 1.8T in October & it has a retractable spoiler. It can be put up manually but it's supposed to come up automatically at 93mph. I haven't had the chance to test that out yet, though. Not sure about installing them, though. Once I get the chance to use it for what it's meant for I'll know more about whether it's a good thing to have. As of now, it's convenient to have open & wash under.
