I went to Best Buy and the 771xv alarm comes out to $600 with installation. They don't have the 791xv. Anyways, I talked to the guy who installs the security systems and he said that Best Buy wont do it on manual transmission cars . He was pretty kool though. I asked if I could sign a disclaimer or something, but he said its been done before and businesses have still been taken to court and lost. So they wont do it, even with the disclaimer. Any ideas?
