Despite the on-off nature of President Donald Trump's tariffs on U.S. trading partners, among those that still stand is the 25 percent import tax on imported vehicles that went into effect on April 3. Wall Street and automotive industry analysts foresee massive global implications for the industry if these tariffs remain in place, with vehicle sales plummeting by millions as prices for both new and used cars surge, according to reporting by NBC News. Research reports put the increase in costs for the automotive industry due to Trump's tariffs in the region of $100 billion, with Boston Consulting Group putting the upper range at $160 billion for both U.S. and non-U.S. manufacturers.
