首先我們(men)看(kan)外(wai)(wai)觀(guan)(guan)，就是(shi)看(kan)車(che)子(zi)的(de)塑(su)料(liao)件，拍打一下(xia)塑(su)料(liao)外(wai)(wai)殼(ke)，如(ru)果(guo)聲音渾厚的(de)話，證明外(wai)(wai)殼(ke)厚，會(hui)耐用一些的(de)。然后(hou)看(kan)一下(xia)外(wai)(wai)觀(guan)(guan)的(de)烤(kao)漆(qi)，是(shi)不(bu)是(shi)均勻，如(ru)果(guo)顏色很淡，可(ke)能車(che)子(zi)就是(shi)庫存貨，放了(le)好長(chang)時間的(de)。接下(xia)來我們(men)可(ke)以(yi)看(kan)一下(xia)外(wai)(wai)殼(ke)的(de)拼接是(shi)不(bu)是(shi)有(you)縫(feng)隙，螺絲什么的(de)有(you)沒有(you)擰緊(jin)，這也是(shi)考量做工的(de)一個標(biao)準。外(wai)(wai)觀(guan)(guan)看(kan)完(wan)，我們(men)可(ke)以(yi)看(kan)一下(xia)車(che)子(zi)里面的(de)大架是(shi)否有(you)焊接不(bu)均勻和脫(tuo)(tuo)漆(qi)的(de)現象，如(ru)果(guo)脫(tuo)(tuo)漆(qi)嚴重，則有(you)可(ke)能是(shi)翻新車(che)。
