In my honest opinion I don't think you can find a better kit for garage tools and equipment than this one. The front of the box doesn't reveal all of the extra equipment that comes in it. Not only does the kit contain an amazing Snap On tool box, but the prize of this kit was the car lift and engine crane. When I first examined the box, I noticed most of the language was in Japanese. I did notice a label of 1500 on the box. I quickly discovered that 1500 is the number of parts in the kit. The suggested age for the kit is age 15 or older. I quickly understood this skill set label to mean this was a skill level 6 set. There are only four trees in the kit I believe but the attention to detail painting is extensive. It took me about two weeks to get all the parts painted before any assembly took place. Once I got the parts painted I started assembly which took another week or so. If you focus on doing a great job with detail painting the assembly is not that bad. Some of the very small parts have to be removed from the tree with a lot of care and patience. This was a great kit and I already have another kit ready to be put together. It will be a while before I get to it. Expect to work on this kit for at least two or three weeks. But the end result is well worth it. The box can be deceiving because it contains a complete garage and not just a few parts and equipment like the front of the box displays.
