Will I get approved for a car loan?

Some details, I'm 21 with a credit score of 744 and I make $5,800 gross a month. I am currently financially responsible for half of a $210,000 mortgage. After my bills every month I have around $2500-$3000 left over. I'm looking to purchase a used car for $43,509 with $20,000 down. What are my chances of getting approved and is it a financially irresponsible decision? Cars are my passion so I seem to try and rationalize spending that kind of money in my head. Need some opinions/answers! Thank you.
