Looking at buying a RHD BJ46 in Japan. I have found two, one is my favorite color red and has a 4 speed while the other is blue and has a 5 speed. Trying to decide if one is a better buy. It will be used for daily driving in Japan and the occasional highway where the max speed is about 65 and eventually bringing it back to the U.S. where it will be used for back woods travel and the occasional interstate drive around WV and PA.
