Investing for profit, IMO, should be dispassionate. Stocks are a perfect example as emotionally, one is not so much linked to the corporation from which the stock is issued and consequentially, maintain an idea of the stock's value. Other factors determine the value.

OTOH, investing in cars is very subjective. When a person thinks subjectively about the value of their investment, more often than not, unless dealing with an even playing field of investors who understand a certain car's value, another person may not consider the car in the same way as the owner. Your $1M car may only fetch $750,000.
