Why do we live? Everyone has his/her own answer.
When I'm stressed, I don't feel alive. If the car will reduce my stress, I'll go for it. If it will increase the stress, I'll do without.
If I can use the money I have to make more, than interest payable on a loan.. I'll take the loan. If not, and I'd rather avoid the stress of a bank loan, I'll use my cash.
That said, I bought my first car, cash. I was very young then.
