The main thing I'm looking at are prices and availability for ICE replacement parts. Its tough enough to get components to make a new ICE car considering the thousands of specialized parts and fluids that it needs.
Will this create a mini-boom for ICE repair people as they can basically charge whatever they want for the one component that a customer needs, or will the consumer simply throw up their hands and chuck the ICE engine in the dustbin of history. I mean, its like "gold rush" all over again, where if you want an o-ring shipped to alaska, its going to cost you $300.
