Euro / grey-market cars versus US-spec

Euro-market 6.9s are more powerful and carry the nicer covered headlights, slim bumpers, and dash-knob-adjustable suspension height that US federal rules deleted, most of which can be added back to a US car. Grey-market examples are described as tricky and caught in a value grey area, carrying a risk discount that can make them real bargains, while the big money now wants a true US car or a documented direct Euro import.
