Nope, it is only in instalments. They did it for just this reason, to stop people spending it on big purchases instead of baby essentials which it is designed for.
I thought it was more to stop irresponsible parents blowing it on pokies, alcohol or drugs?
I can understand why the OP would prefer it in a lump sum as getting a car that safely fits all the family is important.
Op- you might just have to put it all in a savings account, by the time its finished being paid you would have a little extra, plus it would probably be close to tax time so you would have a decent amount for a car.
Best of luck.
