Like - what oem parts or systems aren't working any more? For me its mostly electrical.
The switch to turn on the dome light in the hatch door.
My high beam switch. I can 'flash' but not use my high beams without holding the stalk back.
My 'D' AT light on my dash
You do know that your brights latch on by pushing the stalk forward, right? The pull-back feature is intentionally momentary for flashing.
My "D" light doesn't work on either 80, and I'm glad it's out - I like dim dash lights for driving at night.
My 96 has a rough idle that I've not looked in to. No solid suspects in mind yet. 160k with fresh-ish HG and many other parts.
The 96 muffler is falling apart internally, and the rattle is very, very obnoxious. Home-brew exhaust likely coming soon.
The 96 also has a twisted sector shaft that I need to upgrade with 105 ($$$) parts...
My 94 has a bit of a transmission flare when getting back on the throttle after a turn. It does have 303k on it though, so...
The 94 will probably get new exhaust near the time that the 96 does, because, well, 303k.
The 94 has a leak in either the windshield or a sunroof drain. Driver side A-pillar gets wet. Haven't investigated, but I'm hoping it's the sunroof because the windshield was replaced "properly" about a year ago.
The 94 is ugly. Someone should fix that.
