I am not asking you to wreck your balance sheet lol. Personally I only buy what I can afford and save the rest so it can work for me. Without a car, I would find traveling around very inconvenient so the cost is something I can live with. Of course, I am not going to buy a expensive car but something that will get me by.

However my opinion is that I should pursue the best ROI I can get. This means if I have to consider the small amount of interest on a mortgage payment versus the risk/reward of the stock market, I would pick the stock market. No investment is purely risk-free so I just pick what works best for me.
