I want to start an auto spare part business but i am completely a newcomer in this field. Neither I have any experience of this field nor do i have any body who knows about auto industry. I have some of these queries: 1) what are the things that i should keep in mind before starting auto spare part business? 2) As there are hundreds of cars and thousands of spare parts, how to decide which spare parts should i buy to sell in my store and in what quantity? 3) From where should i buy genuine as well as low cost spare parts? 4) How to decide whether i am being charged genuinely for the spare parts (genuine as well as low cost) that i am buying from the dealer to sell in my store or am i being cheated? 5) How to zero in about a potential and good dealer of genuine as well as low cost spare parts? Please help me with your valuable inputs. I will be highly thankful to you all.
