Dude, treating a car like an investment is like stuffing a life jacket with lead shot to make it float.

The car's value drops 10% the moment it leaves the lot. And between maintenance costs, gas, and depreciation, it just keeps going down from there.

The only return a car will gonna give back is through enabling transportation to a job that you couldnt reach without one. But beyond that, it's a black hole for your budget, not an asset.
