I thought skylines weren't legal in the states and they were being seized by the cops? (I may be wrong but that's the impression I was under)
Certain Skylines were illegal in JDM form for ownership because they didn't meet crash test standards and weren't safe for public roads.
This isn't new, so many car manufacturers got around this by redesigning vehicles to be sold in the US market by adding safety bumpers, integrating energy absorbing inserts in key areas, or completely making international only trims and body styling.
Hmm reminded me of the old 911 bumpers
Still can't believe there are even multiple options for cars...
