Deductions & credits

This is for a regular passenger car registered in MA. From the DMV..... 

You may be able to take an itemized deduction on Schedule A for any tax related portion of the registration fee. To be deductible, the tax portion must be based on the value of the vehicle and be charged on a yearly basis.

But I would not worry about this too much since the SALT restrictions in this section is capped at $10K .. so if your RE taxes and state taxes already exceed that amount just skip this item.
