I must be very lucky. My 2003 S has just under 120,000 km or about 75,000 miles and unless the previous owner changed them, which I doubt, it has the original coils. It had about 45,000 miles when I bought it. I changed the plugs at about 60,000 miles and inspected the coils but found no issues. In my 8 years of ownership I have never had a misfire of any kind. The car is driven from April to October (it’s being put to bed today for the winter).
Perhaps never being exposed to salty roads or harsh conditions makes a difference but it sounds odd to me that coils need replacing as often as they do for some cars.
