Buying car sometimes depends on lucky also.

I suggest you to go to Mazda SC to check the car servicing records. This year probably being the last year of the warranty period (5 years).

If you are in KL, find out any reliable third party workshop who can diagnose and service Mazda cars.

For a 5 years old car, expect to fork out some money to repair those worn out parts like absorbers, bearing, all the fluids like brake, engine oil, steering, coolant, etc
