一封求说服的询盘，亲们有何妙招

公司到如下一封询盘，亲么，你会如何回复呢？ dear , i really would like to know about the quality of the fuel injector for kia pride you had offered. i must know the facts about the quality as we are seeking high quality only. now, by just saying that, many china supplier/manufacturers claim their products are of good or high quality. this i will not buy. i need you to convince me about your quality. look for reasons how you can do that please. i want to let go with korean made fuel injectors and replace it by high (oem) quality only.
