Schwarzman runs Evans in his M3 and swears by the stuff. It's lifetime fluid and since there's no water, you can run it at a lower pressure. I however, decided not to use it for a few reasons. It's expensive but it is a lifetime fluid so this is fine. You have to completely flush everything and get all of the water out. If Evans does spill or leak, it's expensive to replace and is not readily available. Also, if you do go Evans, make sure you're the only one working on your car because it's easy for someone to unknowingly top off your system with water/coolant...then you'd have to go through the entire process of flushing and filling again with Evans primer and Evans. $$$
In the end, I just decided on strictly distilled water/BMW coolant changed every 2-3 years but I do like the concept behind Evans. I just need it to be readily available. If it finds its way into an autoparts store, I may revisit switching over.
