Please help me get my money back!! Ideas?

[84 400]

Okay here is the backround.... As some of you know I got a 77k10 in December. I traded my 1962 wheel horse 552 for it. The truck was non- driving and had been sitting for 8 years. It has low millage of around 28,000 but was a farm truck so it has seen better days. Plans are maybe a small lift and 33's with sheet metal replacement and an overall clean up, 02 gmc dark green paint job and black painted wagon wheels.......

Anyways I got her running good and decided to tag and title the truck so my father can drive it to and from the train station in the winter.

Well here in lies the problem: When registering the truck the "great state" of Massachusetts calculates sales tax acording to 5% on the average resale price according the the NADA value. Now the vehical is older then 25 years old and considered to be an antique so they must use the collector car value. The average retail of a 1977 k10 scottsdale stepside WITH OUT a/c, tilt,power windows or locks is ................ $9,500.00!!!!!!!!!!!!!!

So the state taxed me on 5% of $9,500.00 which is around $500.00. This is criminal. I honestly traded a lawn mower for this truck. Anyways... the RMV told me I can file a abreavement with the department of revenue and possibly reclaim some of this sales tax money. So We have the form and want to build a case to submit to them and I thought some of you might be able to lend some helpful truck info.

I plan on including a copy of the bill of sale, the previous owners phone number for them to call, pictures of the truck, the print out from the NADA guild.

What else might help my case??
What was the Brand NEW retail value of a 77 K10, stepside, big 10 HD suspention G80 rear 12bolt, th350, 350 4bbl trans 10 bolt corperate front np203 full time 4x4, quarts clock. It has no other options that I can find.

How many where produced?

currently I have not located any in my area in similar condition to show the ads for.

I emailed NADA but got no response from them.

This truck does not even meet there guild line for low retail value.

Any advice would be great. I put this in the 73-87 because you all know them best and like me know there is no way this is an accurate value estimate.
