Does the car have a VIN number? NYS may not accept the manufacturers numbers and require you to fill out form, MV-272.1 and get a state run Vehicle Examination (they look for stolen parts and equipment compliance).
You can call DMV Technical Services at 518 474-5282 they are very helpful. Also go onto
www.nysdmv.com for other forms and info. (form MV-272.1 not on web site)
