Gonna do the install today. I didn't want to fuss with it, but my local auto repair shop down the street wouldn't do it because they only do repairs/installations on jobs they can warranty. Not even going to bother asking the Buick dealership as they'd probably charge me an arm and a leg for the install.
I've watched the installation video on the etrailer site several times now, and the more I watch, the more confident I'm feeling about not screwing anything up. :-) Only thing I'm missing is a torque wrench, so off to the auto parts store I go.
