I fully agree, and now, and also of the opinion that used cars market ka bera garak karnay mein, meray khayal mein dealers ki bjayeye, general public ka zyada qasuur hai!
Once I was discussing this dealer aspect with one of my very close friends, and he told me some new, and amazing things. He said that reputed cars dealers / showroom owners have very reasonable, but narrow, neck-to-neck margins, e.g. if there is an xyz car, a dealer will say that I will buy it at 1330, and if he has that xyz car, he would say that he would sell it at 1380 or 1390, etc. at max. 1400, but not more (it may be noted that condition of that car is same in both cases).
2ndly, if any car does not gets sold, then kisi b dealer ko ye baat achi nai lagti k car showroom p khari rahay and bikay na. Khari gari mein dealer ko koi faida nai, rather nuksaan hai, because he is paying the rent of that commercial property in many lac Rs. And would always want that any / all cars leave showroom floors ASAP.
Purani cars bikk jyein, nai aa jyein, and ye silsila chalta rahay; showroom owner / dealer ka issi mein faida hai, otherwise, if a car does not gets sold, then iss mein dealer / showroom owner ka khassara hi khassara hai.
