OK... here's a reality bomb for you. The likeliness will NOT increase. Or at least, it is fairly unlikely to increase. Many people who receive a car allowance spend MORE than that amount. It's quite common. The Tax Man has no business telling you how much you can spend on a car - it's like when people buy say a $200 pen for work. They can claim it as a tax deduction because it relates to work, even though the 'normal' person might think it excessive. Also, the kays you do in the car needs to be business-related for you to claim them, regardless of whether you receive the allowance or not. To and from work is NOT business related.
