I already regret posting this on this board (or at least regret giving the details of the car) since there are so many people on here with serious financial issues who I'm sure don't want to hear my whining. I only posted because I thought I had some insight to share.
To answer your question, Mom, I started looking at cars this March when my transmission went out and I had to spend $3,500 fixing the Acura. Before that, I tended to pretend that new cars didn't exist and told myself that I would just drive the Acura until it hit 200,000 miles (which would take me more than a decade given that I drive only 100 miles/week).
I guess that I just started wondering why, exactly, I kill myself with a high-stress job if I'm going to live way, way below my means. Part of this is due to the fact that I don't have any defined financial goals beyond saving for retirement and paying the house off in 7 years.
It sounds like you're a pretty high earner, which is great. If you have more money than you know what to do with, have you thought of making early retirement a goal? Especially if your job is high stress, that could be a huge asset to you over the course of your life.
That would also give you a lot of focus and incentive to continue saving, knowing that you could retire 5/10/15 years early.
To me (obviously you have to decide for yourself), I'd take early retirement over expensive purchases any day. Not so I can sit around do nothing, but so that I could travel and join causes/initiatives which matter to me without the need to worry about money.
