Not all cars lose value so fast; you know, that whole "resell value" thing.
For example, a new WRX will cost you less than a used one from last year. Those cars just don't depreciate much.
A $100K AMG Merc from 2003, you can get one for around $20k now if I'm not mistaken.
While the circle jerk ensuing is fun, it can realistically be expected certain cars values will not fall as much as they do. Perhaps getting car made by Subaru and Toyota, two brands with very good resell value, led OP to believe this.
