Of course, if foreign car makers raise their prices, that will give domestic car makers room to raise theirs. From Jacob Burg at The Epoch Times via zerohedge.com:
President Donald Trump said on March 29 that he did not ask automotive CEOs to avoid raising prices in response to sweeping tariffs and that he “couldn’t care less” if they do so on foreign-made cars.

The Trump administration is poised to levy 25 percent tariffs on all foreign-made automobiles and components on April 2, with temporary exceptions given to companies that import vehicles or parts under the United States-Mexico-Canada Agreement (USMCA) until the government creates a process for applying those duties, according to the White House.
Trump made the comments in a Saturday phone interview with NBC News. He was asked about his recent message to automotive industry executives and whether he warned them against raising prices.
“The message is congratulations, if you make your car in the United States, you’re going to make a lot of money. If you don’t, you’re going to have to probably come to the United States, because if you make your car in the United States, there is no tariff,” Trump said, adding that he never told them not to raise prices.
