It's phenominally expensive at this point due to the american dollar not holding up well. From when I last checked the conversion rate for this car kit it was over $700 for it. The X10 was pricey also but it seems the US dollar isn't holding it's own against overseas currencys. It seems since the X10 came out the conversion rate has gotten even worse. The last time I bought parts for my X10 some of the parts I bought in the past were noticably more the last time I bought them. It fluctuates, now isn't a good time for the mighty dollar, lol.
