$50k, plus taxes.
You bought a car for $2k, but it was a used car. The fair comparison might be a Nissan Versa S, the cheapest new car in America at $12,780. Or maybe your car has more features than that, I don't know. That still puts the Model 3 at a multiple of the cost of that car, but hardly to an insane extent. Hell, in California you can, today, with rebates (yes, you have to pay some money up front) buy a new BMW i3 for about $22k. Of course, that's a particularly limited electric car, but then again, it also has features a $12,780 Nissan Versa does not, so you could argue the Versa is also limited.
We're not there yet, but we're getting there.
Actually a better argument from your point would be that the mandatory reverse cameras, airbags, safety cells, safety belts, ABS, etc, make new cars more expensive than they SHOULD be. In many countries you can get a brand new car for way less than $12,780. Of course, it's less safe and pollutes more than the new car you buy in the US, but there's a tradeoff in price.
Then again, that tradeoff trickles down to the used market, and pretty soon you have a $2k used car that HN buyers can buy, which is safer, cleaner, and more fuel efficient than an equivalent used car in a 2nd world country.
Or at least, that's how it works in theory.
