Toyota Altezza with 6 speed manual gearbox, can get below rm40k.

Agree with the above, good also to start with cheap cars like the KE70 to minimize the damage cost. Of course to drift, don't put good sticky high performance tires at the rear coz it will be difficult to let it loose. I suggest to practice in a big empty space/parking lot until you can really get a good feel and control of the drift.
