I think repealing the credit may not raise the price very much. If the government is offering a credit, wouldn't sellers simply raise their price to absorb the credit while the buyer thinks they're getting a deal? Without the credit, sellers may be motivated to reduce the price while still making money on the sale.

I saw this in action when I purchased a used EV recently. My choice, which didn't qualify for the credit, was interestingly cheaper than comparable cars that did. Seemed about one tax credit cheaper for some reason. Could be a coincidence.
