I would suggest that you contact the National Street Rod Association in Memphis and get their NorthEast representative's name and number. NSRA could then put you in touch with a reputable person who does appraisals. Usually, these persons are either street rod builders who have an established, legitimate business OR are an appraiser who does street rod insurance appraisals. A regular auto appraiser probably doesnt have the street rod
knowledge to effectively figure what the car is worth.

Another suggestion is to contact one of the street rod insurers to see if they have a person local to you that they use.....Haggerty is one insurance broker who does rods...perhaps other forum folks can suggest other insurers.

As with most sales, a reputable appraiser does not try to buy or sell your car....
