The loan terms on new cars are usually more favorable and you don't have to worry as much about something expensive on the car failing and leaving you without transportation.
I was a couple months out of college when the old car I owned needed about $3000 in repairs that I didn't have. My options were payday loan, buy a new car, or buy a much cheaper used car and hope that it didn't end up needing $3000 in repairs.
New car was the easy choice, and I fully understood at the time that if I could scrape together $3000 it would be much better to repair the car I owned.
It's like buying cheap sneakers from Walmart that you know won't last. Doesn't matter if it's a bad decision if that's all you can afford.
I think paying $1000 for that knowledge would more than cover it. Why pay a lot more not to gain that knowledge?
After working low level internships and restaurant jobs, its easy to get a little too ambitious at age 22 when you sign that first contract with an annual salary.
