A number of my friends have recently purchased Japanese cars. One of the minor issues that is often overlooked is the lack of ability to tune into any FM radio stations above 90MHz. Since I was working on one of these said cars this afternoon I thought it would be a good time to mention this problem. Among other things, be prepared to replace the stereo if you import!
Even into taking these things into consideration, Japanese imports are still great value! You get way more car for your dollar.
