I respectfully disagree, If "cars" were not an investment, there would be no dealerships selling them, weather they would be new or of the vintage / antique type. Not speaking for all, but there are people out there who lost their a** in whatever investments they may be in, and oftentimes people like "tanagele and enjoyable " investments. And investments may not "make" any money but hold it at a place you won't lose any either, yet your enjoyment is viewed as being worth something too. Someone could purchase a vintage car and enjoy it for x amount of years and sell it for what they paid, kinda like locking in their monies instead of losing it in a "market based" investment such as stocks ect.
marketing talks alot of people into buying anything and some will use the excuse of buying something by putting an investment sticker on it. Buy any car and if you can drive it and sell it for the same price you bought it for did not lock you money, the costs of maintenance and insurance, plates and license add to the purchase price and the amount of money on purchase day due to inflation is not worth the same amount years later when selling the car. if the car owner gets enjoyment driving the vehicle that offsets the cost of everything in my mind.
