(Adds second and third investor comments)

March 26 (Reuters) - U.S. President Donald Trump said

late on Wednesday that the United States will effectively charge

a 25% tariff on all cars not made in the country and that the

new duties on cars and light trucks imported into the United

States will be permanent.

Shares of General Motors ( GM ) and Ford fell in

extended trade after Trump's announcement, while shares of Tesla

initially fell then bounced after he said the tariffs

could be neutral for Tesla.

"I've been kind of suspect on all the tariff talks in terms

of what is going to last, what is a negotiation, what is going

to be pulled at the last minute. My initial reaction was this

tariff might have some legs."

"There's probably going to be some exemptions or

modifications for some of the U.S. automakers... I could see the

U.S. automakers getting some exemptions based on their supply

chains. But I think he may want to see how this works out as

opposed to stopping it in two or three days. That's my initial

reaction, that this particular tariff might have legs in terms

of its longevity."

"These auto tariffs are likely on top of other tariffs on

steel, aluminum, copper and the impending reciprocal tariffs to

be announced on 2nd April. It's hard not to interpret this as

anything but a cue for higher prices and lower growth with a

soft landing becoming more complicated. Countries most exposed

to the new auto tariffs are Slovakia, Mexico, South Korea and

Japan. Keep an eye on stocks of car makers, the Korean won and

Mexican peso."

KYLE RODDA, SENIOR FINANCIAL MARKET ANALYST,

"There are a lot of layers here. However, I think the big

concern is that not only will these tariffs be disruptive and

economically harmful, but it indicates that the Trump

administration's shake-up of global trade won't necessarily end

with next week's April 2nd announcement of reciprocal tariffs,

as previously hoped. This potentially drags out trade

uncertainty even longer and raises the question of how radical a

change to the global trade order is Trump trying to bring

about."
