Your example does not account for cost of living. For example, cost of living in greater Los Angeles is probably double what it is in Louisiana.
$500,000 buys a so-so condo in LA and probably not even in a great neighborhood. $500K buys a 4,000 square foot mansion on an acre of land in Baton Rouge.
If OP is paying $1500-$2000 a month just for rent and utilities then suddenly his purchase looks a lot more foolish. Maybe though he has a great love of eating ramen noodles.
Anyways, people can do whatever the hell they want as long as they don't lean on me for "help" while doing it. I personally think it's insanity to spend 2/3 of a year's pre-tax income on a new car purchase, but that's the OPs choice to make.
Forgot to mention. My 70000 a year income is after taxes! So its around 100k actually
