This is my second 1989 740GL!
I love the car!
Headliner falls on both.
Leather seats wear at entry point (driver's side).
Highway ride is creamy-smooth, firm and luxurious.
It feels solid and safe.
The 4 cylinder is strong and reliable, but acceleration is barely adequate.
Some plastic interior parts become brittle and crack or break off.
On most 740's I've seen, the headliner droops in the rear and eventually tears and rips. No easy fix, but I'm going to try magnets strong enough to hold the material to the metal roof. Any suggestions, fans?
I have found no real QUICK FIX for the loose headliner problem that plagues many automobiles. One suggestion may be to cut the liner in the rear so you can reach up in there and spread some adhesive (very thin layer) to secure the liner. If you want to get fancy you can seam the cut together with carpet seam tape and an iron. This has worked for me in the past, yes you can see it has been repair, but compared to the cost of a new pro installed liner.. note: on some autos, the trim holding the headliner comes off with a few screws...
It's been a while since you posted this so you may have already "fixed" the problem or no longer have the car, but... I had the headliner replaced by a small local shop for $260. I think it would have been $30 or so dollars cheaper if I didn't have the sun roof. It turned out beautiful and kick myself for driving around with a droopy headliner for about a year. I found the place in the yellow pages under upholstery. I was so pleased that I went back to the shop and got a whole handful of the guy's cards. For the next 6 months every time I saw a sagging headliner in a parking lot or at an occasional redlight I'd write a little note on the back of the card and give it to the owner or slip it under his wiper blade. They probably thought I was a nut or owned the shop.
I have a carpet fitter friend who simply laid some floor lyno on the roof with normal fitters glue.
Took 30 minutes... looks like new.
Try it! It looks great..
