Bought E320 new in 2000. Now only 62K miles on it - wife's. I'm getting ready to change oil, filter, etc. myself. (All maintenance done my MB dealers in past.) In researching, I note that owners manual says to change sparks at 100,000 or 5 years. Looked back thru all my MB service invoices, no spark plug change ever. It's way under mileage but now over 9 years old. Should I change them? It runs great, always has.
