Who's to know whats best?

If you've found the car you want and at present can afford it, then go for it

Say you wait for a car you like because you think it will be cheaper in a few months, then the prices rise again? your no better off.

If you can buy a car you believe to be worth 15k now for less than 9k, your onto a winner anyway. Even if the car sells for 7.5k in 6months, your still within what you saved when you brought it.

You could always buy a cheaper economical car and regret not buying the car you really want.....
