No offense, but in my experience most folks here would probably rather put together their own kit. But, if one were to buy a pre-made kit, I would think you would need to put a lot of thought and real world experience into it. Check out Doug Ritter's kits. They'll give you a good starting point. Your list looks to be a bit all over the place. Example: if you can carry a 5 gallon water can (in vehicle), you probably can skip the fishing hooks and just carry some food. There's a difference between a survival kit and an emergency kit. You seem to have a mix. Not that you can't, it just needs a bit of refinement. To give you an example, here is the content list of my go-bag. It's a mix of survival/defense. But, if I'm traveling in the car, I can just chuck in some extra food/water/blankets on top of the go-bag and what I always carry in the vehicle.
