I don't know what people think about going for lots of security. Personally, I just lock the garage door, park in front of it and have the steering lock/alarm on.
I've heard so many stories of theives going to any lengths, that my opinion is - if they want it, no matter what you have, they will take it. You can spend lots on making it harder, but they just come back more prepared. So I just do the basics and I'm insured against any loss. I don't think you can do much more than that. Our neighbours garage was broken into - they got past the steel floor bolt thing with some kind of heat cutter (plasma) as they knew it was full of snap on tools.
