NCD can tell whether the car did claim insurance before, right? Match it with the years of register vs the NCD percentage, then can roughly know whether there was accident before. ofcoz provided that he buy it as new 100% before.
let say there's a car 2015 register, NCD 100%, then you know that it just claim insurance. it might not be 100% accurate , but it helps

Well, things is when surveying for used car, you not going to just check 1 ... that will add up the cost quickly.
If it's like the SMS, RM0.50 and RM2, then it make more sense. but I tried the 36600 sms, it's not working.
