I'm 12 miles over 500miles on my 2007. I failed to read all the things that are suppose to be done via the owners manual, as well as it suggest having it done by a competent mechanic. I changed the oil and oil filter, but there are a few things that I do not have a clue on. Are all the items of great importance? Could this void any warranty or discourage someone from buying it in the future if I don't take it to a dealer for the 500 mile maintenance, or am I just being paranoid? Thanks for the input.
