Why don't you just borrow money to buy stocks, without involving the car? You can get lower rate if you use your own stocks as collateral, i.e. if you use brokerage margin. Heck, these days margin lending is so crazy common that there are even ETFs that package leveraged equities for you to go anywhere between -300% via 0% to 300% long, just change the allocation with a few clicks (or taps on your phone).
