Value question of my Father In-Law's 71 Cutlass Supreme Convertible

[njsteve]

UPDATE: Wife just got back from the In-Laws house. Has the original dealership owner's manual glove box folder with the original Window Sticker in it, The folder has the original owner's name on it. Found the second owner's NY inspection receipt from 1985 at 39,601 miles. Third owner NY inspection receipt with 57,000 miles from 1995. Third owner's Bill of sale to my Father in law's brother in 2000 (Fourth owner) and then my Father in law (Fifth owner) getting it in September of 2002 with 59,000 miles. So my Father In-Law put 40,000 miles on it is 23 years. I'll post the new stuff in the Olds thread. Go check it out! https://www.yenko.net/forum/showthre...13#post1675713
