Since you already have a moped, ask yourself:
1. Do I actually need a car?
2. Is the superbike a luxury purchase?
3. Do I need either one immediately or can it wait?

Sorry to be blunt, but these are hard times. If you don't need either urgently consider saving up first. At least you'll get more bang for your buck in terms of specs-per-ringgit when the economy improves.

Not really, no. I urge you to hold back on the purchase, at least until things look a little better. Plus, securing a loan is getting difficult with most banks tightening lending requirements. Unless you're earning over RM4500 with no existing commitments, you may not qualify.

If you're going to ignore most of the advice here and buy either one anyway, get the car. It serves more utility than a superbike does.
