Ask an Adviser - Should I Spend Some Of My Savings For A House Deposit On A Car?

Hello, I'm currently in 2 minds as to what I should do in regards to whether I should borrow money to purchase a new car or use some of my savings which I've put away for a house deposit? I'm hoping to start applying for home loans in a few months time but I'm in need of a new car asap. I'm only looking to purchase a car used for around $15k but don't really want to touch my deposit for a house. Will the banks look at me having a bigger asset in a $15k car better than not having a car at all even though I do owe money on the car? I currently have no debts whatsoever and no credit cards… any help would be great.
