please be very careful whle choosing a second hand car. the most common things that you have to be very careful is flooded car & accident car. They will refurbished it till you did not notice it was accident or flooded car. If you can make a friends with very good workshop mechanic, they can come with you to check the car together. normally it will cost RM200-500 depending on experience. You also can bring that car for inspection for any faults before purchasing. You can bring to any desired workshop for that. It will cost you around Rm100-150. Btw, Regarding the milage, 90% of the car that you bought from the used car dealership had been changed. Dont trust the milage! You can get the original milage during inspection by 3rd party using computer. Please let me know if needs any help!
