BTW, my car has 196,000 miles on the orginal coils.
Ill definitely pass on the coil change! at $300 for a maybe? I definitely will throw it towards something more useful. I was just nervous though because OP mentioned to one of the posters about replacing it as preventative maintenance or something like that but if you're already at 200k and still haven't changed it, I should be good for a while longer. How is your driving style though? Don't those factors also contribute to whether you'd need to change plugs, oil, etc. Differently?
