its common sense thats my source. you buy a new car and value drops right away. how thats a good investment? most of the time you pay more for a car than its worth if its brand new. dealer markups and fees
a $9,000 hyaundhi will get your from a to b just like a 100k audi will. you buy either of these cars new and the value drops simple to understand. but the more expensive one drops more $$$$. maybe if you hold onto a saught after low production car for 50years in the garage and let it sit you might make money unless you die beforehand. and having a car you cant drive is weak shit.
im not saying a hyaundhi is better im just saying cars are bad investments for most. you loose money almost everytime. insurance, maintance, taxes, intrest, etc all cost you while driving not to mention inflation. thats not a investment to me. gold,silver,food,guns etc is a great investment
might be a couple exceptions like a truck driver or pizza boy who need a car to make a living but they make up very few. and i wouldnt consider them most people. most people in us work for the govt at a desk
heres a couple good reads http://www.forbes.com/sites/investopedia/2011/02/11/buying-a-car-the-worst-investment/
but i would ask yourself the question again…is a car a good investment or a bad investment?
