that price is fine. i pay that for an oil "service"
I'll never do it myself. i prefer to drop it off at the dealer, have a coffee and a muffin and pick it up all good and ready to go.
Doing it yourself is just a recipe for breaking smoething, otherwise the owners manual would have an index page for "How to change your own Oil" etc. etc.
and, i wouldnt be able to find it anyway. my car has a big fat engine cover over the whole engine and im not even gonna try figure out how that thing comes off, thats what the dealer is there for
