maintenance parts that cannot be matched.
We have all found good deals on "like new" or new parts and at the end of the day if we "choose" a shop to install those parts then that should be reward enough for that shop... a surcharge would definitely offend me.

Yea, though I drive in the Valley of the Shadow of the V8, I shall fear no V8 for the V6 twin turbo is with me. Thou shall prepare boost at my call against the V8 that troubles me. Thou annointest my V6 with Motul Oil and Shell 91, and my psi shall runneth over. Thy loving smoothness and torqueness shall follow me all the days of my driving and I will dwell in the house of the V6 Bi-Turbo forever.
