When the Tesla Model X was new, the popular 90D version cost about $100,000. Thanks to the magic of depreciation, though, the cheapest Model Xs can now be found in the $15,000 range. As far as practical family cars that still run and drive go, a price like that is hard to beat. And if you want an electric three-row family hauler, it's your only choice south of $20,000. That makes it a tempting buy for people with a limited car budget who have gotten sick of playing gas price roulette.
