Lexus dealer wants to charge $500 to replace spark plugs on 2003 RX300 , is it because it is very labor intensive ?
IDK, but this forum topic might interest you: http://us.lexusownersclub.com/forums/topic/31597-changing-the-3-rear-spark-plugs-in-the-rx300/ , my take is $500 to change spark plugs is an absolute ripoff.
...thats a rip off.. find a shop with 1/3 the hourly labor rate..
