There's more to it than that.
The big catch when importing a complete car is meeting the DOT laws. This is where it gets expensive and stupid.
In the 1980's it was very popular to buy European high end cars and ship them to the USA . (grey market cars)
The dollar was strong and you could make good deals on cars such as the 911 turbo or 500sl.
Only problem was that you had to take it to a "government authorized" shop for the DOT/EPA conversion.
This is where they would install the US version headlights, a seat belt wrning buzzer, impact bars in the doors, etc.
The drawback was that you paid ridiculouly high prices for some of the worst hack up jobs I have ever seen.
I have worked on many grey market cars, trying to straighten out and fix the butchering some of the cars have gone through. I have seen catalytic converters mounted in a way that could easily catch the car on fire! Air/smog pumps mounted by hanging it off of the alternator.
Carbon cannisters for the fuel system mounted with tie straps, etc.
The sickest part is that it can cost from 5 to 10 thousand dollars to do the DOT conversion at these shops.
There is a list of the "authorized shops" on the gov't DOT site somewhere, as I used to have it.
At one time, I wanted to bring a rare model Mercedes to the states & called to DOT to see if I could do all of the conversion work myself, and then have it inspected.
NOPE, you must go through one of the shops on their list.....even if the car needs nothing done to it, it has to be processed through one of those listed shops.
This is what I experienced about three years ago,,,,,so some laws may have changed since then.
