When I think about putting cars together, I think of two things: built-it-yourself model car kits and taking my car to the mechanic. The complexity of a "real" car is often what keeps novices away from tinkering with them - along with the fear of not being able to get it back together properly. Mitsuoka Motors, a Japanese auto company, just introduced the "K-4", a micro car for one that you can assembled yourself with the instructions they provide with it. The K-4 is ideal for those who want to be "hands-on" with cars, or just don't have need of a full-sized vehicle. It still takes about 40 hours to put together the 500+ pieces, but it looks to be easier than a conventional vehicle. The car is about 8-feet long and has a maximum speed of 31 miles per hour. Price (approx): $6,460.
