Well if that car enabled me to get a job at McDonalds that I would not have otherwise been able to because of commute distance, then at a nominal $17,000/yr pay from that job over ten years would be $170,000 gross income. Minus the $19,000 initial investment and let's say $3,000/yr in fuel, insurance and maintenance I'd still have $121,000, versus $95,000 from stocks. (I'm not sure having my soul crushed from working ten years of minimum-wage burger flipping is worth it, though).
Of course you can't exactly sit around waiting for those stocks to ripen, can you? The moral of this story is a car isn't an investment.
Also something something opportunity costs, something something net present value....
