I'm checking into the Ghost II system and fortunately for me, there's an Autowatch authorized installer in my city of just over 1 million people. They checked and told me they can do an Emira installation. Thanks
Andy H for the helpful info about the "gearbox lock". I look forward to your advice about potential warranty issues, in due course. I"d be surprised if there'd be any, since it's a stand-alone system, as far as I know.
I think getting the Bluetooth Key Tag with the system, is a good idea, so you can provide that to any dealer servicing the car. I realize you'd have to trust the dealer not to download the code, but I wouldn't have a problem with that, since I'd already be trusting them with my vehicle. I suspect the code could also be changed, once the vehicle is back in my hands.
FWIW, I also checked with my vehicle insurer, who's on the list of companies that provide a discount with this type of immobiliser. Once installed, I'd save (drum roll...are you ready?) a grand total of $24/year for my Emira policy. At that rate, the Ghost II system would pay for itself, in about 58 years. I can hardly wait (lol).
