The parking challenged take note: the Laser Guided Parking System can help you pull into your garage perfectly. Mounted to your garage ceiling, the system detects when you come in and emits a laser beam pointing at the perfect stopping point to ensure you don't pull too far forward or to the side. You select your own sweet spot say, a point on top of your dash and mount the laser to target it. Then when you pull in, watch the beam slowly drift closer and closer to the spot, sort of like Indiana Jones in the map room in Raiders of the Lost Ark (soundtrack not included). Once you hit the bull's-eye, put 'er in park. For those who've ever dinged a fender or lost a side-view mirror because of poor garage maneuvering, a laser parking aid is probably worth $25. You just need a Philips screwdriver to install it.
