The dollar's weak exchange value against the euro is wreaking havoc on U.S. foreign trade balances.
It also makes European travel plans more expensive and could prompt even greater price hikes for European cars sold in the United States.
But the weak dollar also is helping Cadillac get a toehold in Europe.
The strategy is to price Cadillac models as much as 15 percent below competitive models from BMW, Mercedes-Benz and Lexus, according to Automotive News Europe.
Meanwhile, as part of the strategy to make Cadillac a global brand, General Motors also is trying to expand Cadillac sales in the Middle East. This year, GM expects to sell 2,500 Cadillacs in the Middle East region, where the brand has a more traditional, upscale image. Annual sales could hit 4,000 within a year or two.
Cadillac's independent distributor in Europe plans to import 6,000 of the luxury cars this year, 7,000 next year and up to 20,000 Cadillacs a year within five years.
At some point, the dollar will rebound against the euro. But by then Cadillac should have right-hand-drive models to sell in the United Kingdom and an owner base on the Continent.
And I'll bet you thought a weak dollar was a bad thing.
