With 200K i would replace it just to be sure! Its plastic, and if never replaced its only a matter WHEN it goes! Save yourself the hassel of towing, being stranded, etc etc! It will end up costing way more if it actually goes bad, not to mention the potential risk of blowing up an engine (seen it many times!)
PS i got 260K on my coupe, with NO issues for the window regulators, but had to replace the swith! My friend had the same problem on an 05 330ci with only 115K!!!
