^Don't give in!
The only way you'll know for sure that it was done right is to do it yourself. If ramps are an issue just use a floor jack and 2 jack stands - easy!
It will be worth it to do it yourself. For both you and the Z.
I was talking to a buddy at work today telling him about the filter mag and the magnetic drain bolt and he thought they were cool mods, but was sure that they would be "gone" after the first oil change (he takes his in). He's probably right, out of ignorance or disrespect these extra steps that some have chosen to take would mean nothing to most oil change techs.
I shudder at the thought of taking my Z to someone else for the basic maintenance that I am capable of doing myself. I still hate taking it in even when it's something I haven't yet learned to do. I just know that no one is going to be as careful or thorough as I would be with my stuff.
Rant over.
