NH requires 2. Hey, if I have to pay $430 to register my car, plus another $45 for safety inspection, they ******* well better give me two plates!
Oh, and the inspection process here doesn't include smog, but they will fail you for little shit like body rust or brakes, etc.
And before ya'll tell me how expensive that is to register my car, let me state for the record once again--NO STATE SALES TAX. Buy a $25-30K vehicle and how much in sales tax are you paying for that car? I rest my case.
Poor BEG--buy a car there, and not only are you paying the 9 percent-plus sales tax, but the Godawful registration fees, smog, and gas that runs around $3/gallon for regular (ex is bitching about paying $3.25/gal for premium) while I'm paying (in some spots) under $2.40 for regular.
