Can I cancel my order if contract is signed?

So I may have rushed into signing a contract for Geely EX5.

Still haven't taken the delivery of the vehicle and was told it would be available at the end of June/early July.

My novated lease provider got me a very good deal at one of the other dealerships they deal with for the same exact car.

I have put a $1000 deposit and am hoping to cancel my order as it is saving me almost $2400+.

Can I cancel my order? Will they give me the $1000 deposit back? Has anyone done this before or has an idea how I can get around this?
