I never really cared about any of them when new but have a soft spot for any older 80's/early 90's GM in good shape, because you just never see them on the roads anymore. Talking about any fwd car really, the g-bodies and f-bodies have enough support/interest, even seeing a plain Celebrity going down the road in nice shape (at all really) has me do a double take.
I was impressed with my H Body, a 90'
LeSabre as my daily driver for about 7 years, comfy, good reliable runner, room under the hood if needed to work on it, great sightlines, body held up decently too. Sold it when buying a 02' Regal GS. I'm personally not as impressed with W Bodies based on that, the drivetrain (especially L67) was great, comfy, thought they look pretty sharp but the suspension issues/quality was one thing, rust issues were another. Rocker panels started disappearing when 10 years old, the radiator support rotted out while driving, luckily just enough held in the radiator from totally dropping onto the road. All vehicles rust here but the metal thickness/how quickly that rusted was disappointing. Definitely more small issues than the H Body had, seems the design/build quality in many areas was lacking.
Cool seeing the earlier W Bodies though, the later ones I still see enough, although I used to see GTP's all over it seemed, now they fall into the double take category.
