Okay, I'm new to this car and I have looked all over for the oil filter and the spark plugs. Where are they exactly? Are they DIY or do I need to take it to a shop? What tools do I need to do these items if its a DIY job? Any other suggestions on what else need to be done or checked so I can get a baseline as far as maintenance or things to look out for? Is there available shop manual or CD available for this model? Thanks!
