I've used Costco standard size 27 batteries in my 91S since I bought it in 94, and they last about 10 years or more, no problems starting or whatever. The LS does have a Costco Interstate 31 right now (long story), but I don't think it is necessary unless you live in an area which gets terrible winters. These batteries from Costco (actually made by Interstate) have been satisfactory for years, even the couple of times I've accidentally let the LS battery go pretty flat (forgetting to pull the radio fuse, lol) from not being driven for weeks, without the super high costs of the others.
The earlier trunk lids with springs have no/zero problems with hinges, etc. Don't worry about that. It's the later ones with struts which do. That design is bad news. In fact, I changed my LS over to the earlier spring set up, as I did notice the start of hinge distortion and top of strut rubbing on the inside of the right rear fender.
One more thing to remember. Do not use the spoiler to lift or esp lower the lid, as it is relatively flexible, and the paint on it can crack if you use that (don't ask) especially if you are used to American cars where you generally slammed the lid closed. I have adjusted both 164 lids so that they shut and lock with a light touch, no force necessary.
Most who are concerned about the faded carpet just dye it in situ, and use a pad on it. I think it is probably a pain to remove and replace.
There IS a lockout for reverse in the mechanism which doesn't allow you to shift from 5th straight down to reverse. It moves the lever over to 4th instead when downshifting. The trick we've always used for getting into reverse (our Milano is particularly touchy sometimes about this) is to hold the lever lightly against the balking reverse position, and just barely let the clutch start to engage. This turns the gears slightly and allows the lever to drop into reverse quite nicely without any trouble. Most of the time this is never a problem. Both our S and the LS shift into reverse with ease from idle. Your car should get better with use and you gain experience with the gearbox. My wife's brother has a Jetta, where he is continually fighting to push that knob down to get into reverse. Hangs up or something. Hates that part of the car.
