To me at least, There's a difference, Dennis, between what I like because I can afford, and what I would like if I was bucks up. In my world of turbo Buicks, I prefer '87's, no roof treatment, the sports mirror package, & the limited outside trim known as the "Wide Bevel" option on most cars. On real life Limited's, I don't like the leather seats, nor the 60-40 or 65-35 seats, the shift on the tree, nor the door trim package. I do like the lighted glove box trim.
I do prefer bucket seats, and I like the looks of them better than any other type of seat.
Never was a fan of the chrome mirror package, even though they are super rare.
Theoretically, the '86's should be worth more than the '87's because they're rarer, but in real life it isn't so. Aesthetically & cosmetically, I prefer the '87 package over the '86 package.
You're pecking order might be politically correct to the uninitiated, but not "real world" correct to the people that have owned several of these cars. I've owned 5 of these, and I am not known for my politically correctness. I prefer to be a "renegade".
FWIW, IMHO, & HTH.
