M3 midlife crisis...
 

hello M3 purists,

my 2005 M3 ragtop with 39,000 miles has been uneventful up until now. it started to exhibit this metal clammering sound off and on coming from the rear while in motion. i don't its the brakes. no unusual indicator lights on computer display. and now my left xenon headlight is blown. whose to say the beast doesn't have a midlife crisis....suggestions or insights will much appreciated.
