...purchase soon.? My take home pay after taxes each month is $1912 and after paying all my bills and etc my left over is like $420 on average. I can push to have around $724 leftover if I stop buying useless merchandise like video games that I play for 1 week and never play again. I'm asking because I want to purchase a new car soon since I've been driving a accident happening vehicle for a long time. So, how much % of income I should save up per month? If I manage to save around $700 a month would it be ok to get monthly payments of $500 a month on a nice car?
