Buying a car new is a waste of money anyway. The second you register it, The Invisible Hand of The Market™ swoops in and takes away a good portion of its value. Especially if it's a new model, you're also stuck with all the teething problems associated with any new and untested product.

If you don't want to be ripped off buying a car, you should buy second hand. If you're forced to buy an affordable car due to monetary constraints, you actually have no other choice than buying second hand. But even then, a car is only affordable if you can get a decent amount of remaining service life out of it by the time it has become cheap enough for you to buy. If you buy a 10 years old combustion engine car that's in decent shape these days, you can reliably expect it to last for at least 8 to 10 more years if you give it a little bit of maintenance.

Truly affordable electric cars will come when (or if) the current models are 10+ years old and still have a useful battery life by then.
