50K service - Spark Plugs needs replacement?
Your best bet is to find a reputable local Indy. I was also quoted something similar by the stealer (I meant dealer). Local indy just quoted me 1 hour labor to change them.
2010 550 ml .. just about to do the plugs and they all look easy... besides the last two rear ones. ...
any tips ? .. lol could i just change 6 ?
