Just to be clear on all these; cars, art, jewelry etc are not strictly speaking, investments. They are items on which to speculate. You are speculating that someone will buy them from you at a point in the future for more than your associated cost of purchase and holding them. Investments pay an income with a residual capital value. These items will pay no income, the capital value is all that there is. So you have to be very careful to have a clear strategy around buying, selling and holding such items. I'm not saying it cannot be done. But you need to clearly understand the issues around speculating vs investing.
