Sorry, but this is ridiculous. $60,000 divided by five years (yeah, it will last much longer than that) is $12,000. If you're making hundreds of thousands a year and can't afford $12,000 for a car, taxes are not the problem.
Parent may have been talking about affording the car, not the car payment. It's a classic car sales tactic to get people to focus on the payment instead of the overall price.
