"每年改改外壳" -> Marketing strategy. (Anyone who owns a store will agree on this!), not necessarily "骗钱".
This means those who buy "倭人" cars are not smart???
I think to us, those who have to drive in cold snowy winter (outside temperature can be as worse as minus 20), I want a reliable car, that won't break down on highway. I seldom heard "倭人" cars have transmission problem/failure, even car mileage is over 300000 km.
My mechanics (I have two in Toronto) told me, don't buy A's cars. A very high likelihood to have transmission failure after 200000 km.
