首先我(wo)們看(kan)外(wai)(wai)(wai)觀(guan)，就(jiu)(jiu)是(shi)(shi)(shi)看(kan)車子的(de)(de)塑(su)料(liao)件，拍打一(yi)(yi)(yi)下塑(su)料(liao)外(wai)(wai)(wai)殼(ke)，如(ru)果聲音渾厚的(de)(de)話，證明外(wai)(wai)(wai)殼(ke)厚，會(hui)耐(nai)用一(yi)(yi)(yi)些(xie)的(de)(de)。然(ran)后看(kan)一(yi)(yi)(yi)下外(wai)(wai)(wai)觀(guan)的(de)(de)烤漆，是(shi)(shi)(shi)不(bu)是(shi)(shi)(shi)均勻(yun)，如(ru)果顏色很淡(dan)，可能車子就(jiu)(jiu)是(shi)(shi)(shi)庫存貨，放了好長(chang)時(shi)間的(de)(de)。接(jie)下來我(wo)們可以看(kan)一(yi)(yi)(yi)下外(wai)(wai)(wai)殼(ke)的(de)(de)拼接(jie)是(shi)(shi)(shi)不(bu)是(shi)(shi)(shi)有(you)(you)縫隙(xi)，螺絲什么的(de)(de)有(you)(you)沒有(you)(you)擰緊，這也是(shi)(shi)(shi)考量做工的(de)(de)一(yi)(yi)(yi)個標準。外(wai)(wai)(wai)觀(guan)看(kan)完，我(wo)們可以看(kan)一(yi)(yi)(yi)下車子里面的(de)(de)大架(jia)是(shi)(shi)(shi)否有(you)(you)焊接(jie)不(bu)均勻(yun)和脫(tuo)漆的(de)(de)現象，如(ru)果脫(tuo)漆嚴重，則(ze)有(you)(you)可能是(shi)(shi)(shi)翻新車。

   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。
