Why the hell would you want to change a 9 month old Myvi to another car? Are you that damn rich?

Just keep on using the current car for as long as you can while spending the least money on maintaining and repairing the problems... Later on, when the car really starts to cause lots of trouble, dump it and buy a non-national car...

You might lose more than RM7k, maybe you'll lose RM10k, but you'd have trashed the car and used it to its maximum potential before dumping it, and that means you've gotten the most value for your money!
