ok thanks for the replies! I have a toolbox, with metric wrenches, 7-19mm, sockets (mostly deep) from 10-24mm (with some sizes skipped) and I have an adjustable wrench, channel locks, a 3" extension, a 6" extension, Lug wrench, original wheel chock, original jack tools and jack. I will have a spare tire for the trip...
btw all the tools i listed above, I carry in my car all the time...
the question remains, which items should i buy at the dealership, and which should i buy at the local parts store?
