I've tried a few 2WD buggies in the last couple of years and the original YZ-2 was my favourite. The only reason for selling my YZ-2 actually was to spend less time with RC. Getting spare and option parts for Yokomo cars could not be easier in Germany, Tonisport has offered the best service. If you've got any urgent questions, I'd recommend calling them instead of sending an E-mail, though.
If you are looking for more information on the original YZ-2, feel free to check out my honest review on

The CA version includes most parts I added to the original kit and should be great right out of the box. You won't be disappointed for sure!
