首先我(wo)(wo)們(men)(men)看外(wai)(wai)(wai)觀(guan)(guan)，就(jiu)是(shi)(shi)(shi)(shi)看車子的(de)塑料件(jian)，拍打一(yi)下(xia)塑料外(wai)(wai)(wai)殼(ke)，如(ru)果(guo)聲音(yin)渾(hun)厚的(de)話，證明外(wai)(wai)(wai)殼(ke)厚，會(hui)耐用一(yi)些(xie)的(de)。然(ran)后(hou)看一(yi)下(xia)外(wai)(wai)(wai)觀(guan)(guan)的(de)烤漆(qi)(qi)，是(shi)(shi)(shi)(shi)不是(shi)(shi)(shi)(shi)均(jun)勻(yun)，如(ru)果(guo)顏色(se)很淡，可能車子就(jiu)是(shi)(shi)(shi)(shi)庫(ku)存貨，放了好長時間的(de)。接(jie)下(xia)來我(wo)(wo)們(men)(men)可以看一(yi)下(xia)外(wai)(wai)(wai)殼(ke)的(de)拼接(jie)是(shi)(shi)(shi)(shi)不是(shi)(shi)(shi)(shi)有(you)縫隙，螺絲什么的(de)有(you)沒(mei)有(you)擰緊，這也是(shi)(shi)(shi)(shi)考(kao)量做工的(de)一(yi)個標準。外(wai)(wai)(wai)觀(guan)(guan)看完，我(wo)(wo)們(men)(men)可以看一(yi)下(xia)車子里(li)面的(de)大(da)架(jia)是(shi)(shi)(shi)(shi)否有(you)焊接(jie)不均(jun)勻(yun)和(he)脫漆(qi)(qi)的(de)現象，如(ru)果(guo)脫漆(qi)(qi)嚴重，則有(you)可能是(shi)(shi)(shi)(shi)翻新車。
