首先我們(men)看(kan)外(wai)觀(guan)，就是看(kan)車子(zi)(zi)的(de)塑料件，拍打一(yi)(yi)下塑料外(wai)殼(ke)，如(ru)(ru)果聲音渾厚(hou)的(de)話，證明(ming)外(wai)殼(ke)厚(hou)，會耐用一(yi)(yi)些(xie)的(de)。然后看(kan)一(yi)(yi)下外(wai)觀(guan)的(de)烤漆，是不(bu)是均勻，如(ru)(ru)果顏色很淡，可能(neng)車子(zi)(zi)就是庫存貨，放(fang)了好長(chang)時(shi)間的(de)。接下來我們(men)可以看(kan)一(yi)(yi)下外(wai)殼(ke)的(de)拼接是不(bu)是有縫隙，螺絲什么的(de)有沒有擰緊，這也(ye)是考量做工(gong)的(de)一(yi)(yi)個(ge)標準(zhun)。外(wai)觀(guan)看(kan)完(wan)，我們(men)可以看(kan)一(yi)(yi)下車子(zi)(zi)里面(mian)的(de)大架(jia)是否有焊接不(bu)均勻和脫(tuo)漆的(de)現象，如(ru)(ru)果脫(tuo)漆嚴重，則(ze)有可能(neng)是翻新(xin)車。

   看完外觀，就是電動車的四大件了，電池、電機、電池充電器、控制器。
