Hey friend. I'm also looking for a 2nd hand hatchback.
If your budget is around RM30-40K, you'll have plenty of options.

Mazda 3 2.0 Hatchback - This is my 1st choice actually. For it's sporty looks, Japanese tech and excellent handling.

Honda Jazz 1.5 VTEC - For it's awesome interior design and seat configurations.

Myvi - It's really spacious, cheap to own and extremely reliable.

Prius - If you're into green cars. This is the one to get. With its futuristic tech and all the engineering marvels, the price for this model is really cheap now.
