well if we talk abt that oil filter thingy .... i srslly dont have a solid reason or point to prove that .... every single thing comes up with 4 different qualities .... OEM , Original , A class & B Class ....
da will look like same .... not a inch greater or lesser in size buh huge diffrnce in quality ...
and now ... comming bak to the point of showroom ... well ... people there r muslims 
, pakis , i think dats enough to justify that da can do anything ... 2no parts ka im not sure .. buh u can get 1no part in lesser price with good contacts with the labour 
...
