OK, dumb sounding question, I'll grant you. I bought my little wife a Q7 with several bells & whistles...just not the electronic liftgate/tailgate option that comes as part of the convenience package. she's kind of small and hauling that big gate up and down is a bit of a chore. So, I'm wondering if anyone has heard of a way to retrofit the tailgate to add the electronic / motorized feature?? Thanks in advance...
