Most (prepared) people have a jack in their trunk. Just in case their faithful ride turns out to not be so faithful and you lose a tire. There are many different kinds of jacks, from the classic the types that you just need one foot to operate. The Exhaust Power Car Jack uses your own exhaust fumes to lift your car.
This jack works by slipping it under the car and then attaching the hose to the exhaust pipe of your car or truck. The bag, made of PVC, will inflate and lift the vehicle off the ground with close to no work done on your part. Yes, you do have to spend a bit of gas to run this, convenience costs.
This jack is ideal for dealing with softer terrain like soft soil or even mud. Because it has more area than your traditional jacks, it won’t sink into the ground with your car and actually help you get it out of a sticky situation. Great if you drive a big car in a moist area. The Exhaust Power Car Jack is $258.
