Buy your BMW 3 Series or 2 Series before May 1. Donald Trump's on-again, off-again tariffs will raise new car prices, but some consumers might not immediately feel the pinch. BMW told its dealers that it will not raise prices on certain vehicles imported into the United States from Mexico until May 1.

BMW announced it would price protect its Mexican-built models like the 3 Series, 2 Series Coupe and M2 from potential 25 percent tariffs.

Both the 2 Series and 3 Series are built at BMW’s San Luis Potosi plant in Mexico, then sold here in the U.S. The 2 Series sees every version of it built at that plant, including the M2. However, the 3 Series is also built in Europe,

BMW plans to absorb the cost of Trump's tariffs on the M2, 2-series coupe, and 3-series sedan—but only for a short time.

German carmaker BMW said on Friday it expected tariffs to cost it 1 billion euros this year, while European officials warned the U.S. economy would be the biggest loser if President Donald Trump pursues an "idiotic" trade war.

The automaker expects earnings to remain flat this year while sales will grow only slightly as a result of global trade tensions and a demand shift in China.
