It's terribly irresponsible of the bank to loan her the money with so little work experience behind her.

I got a $5,000 loan at 19 no problems from CBA, but had been working for almost 12 mths at the same place and had been working previously part-time as well. Unfortunately, about 12 mths after buying the car I too had an accident and bye-bye car (thankfully not me, since it was a really bad accident). And no insurance. So I had to repay the loan for another two years without anything to show for it...

Maybe sit down with her and 'help' her research cost of ownership of cars. NRMA website has a function where you can look up this kind of thing (perhaps the V6's lack of a green rating might help if she's at all concerned about the environment?). And make sure she understands how important full comprehensive insurance is, at least until the loan is repaid. With the cost of that for her age and the type of car she's considering it might help your cause.

Good luck.
