There are way more 87 and 88's number wise out there, and the numbers shipped and sold here drop off into the 90's as you guys all know.
That being said here are a few details I like about my 88 Turbo.
The grilles are larger, so you get more air flow. (And I like the open upper grille with no center "rib" like the 89 or newer's have.)
I don't care about avilability of "lips" for this cover. If I want one, Duane makes a very nice one, case closed.
The rear spoilers on my 88 is very tastefully done. The 3 piece ones look fine too, but are not worth the effort to change over to.
Same goes for the lamps. The 89 or later lamps molding does not match the pre 89 cars, so I think it looks less than refined to use them in most cases. There have been a few done right, but only a few.
I think any old car like ours with lamps in good condition looks fine. (Mine included.)
I like my Euro marker lamps with the bubbles, and my Euro folding mirrors
(This is one case where the JDM ones totally don't work, the angles are all wrong for LHD.)
The 89 USDM had the second best steering wheel to the original 3 spoke used in my 88. The problem is most of the 88 wheels are falling apart now, and nobody has an easy way to recover them. (I'm thinking either a nice Momo wheel, or spend the same money to have a custom leather cover that is cut and laced to fit my stock 88 wheel perfectly would be a good idea.)
Besides, on the pre 89's the HAC is where it's supposed to be. (Nice for us Maft Pro users... LOL)
