Harbor Freight...$20...I only have one deep socket, but I'm surprised you need them for the M vcg. You sure about that?
Anyway, as a principal, it almost always pays to get the tools rather than to pay someone with the tools you need. I haven't needed a new tool in years...but you should have the tools your car needs, by and large.
I'm so depressed. No one wants to come see me. :(
Mangofy your E46!
