Hi, long time since I had my 1992 Ls400 BUT my memory might be playing tricks on me .............
The steering wheel isn't telescopic
The mirrors aren't moveable electronically either........ your hands do the moving !
The dash needs soldering in the circuitry ..... Chris Vince on here is the expert to do it for you if you're not able to repair yourself. He's on here and lives Farnborough Hants way, You can take your car there and he will zap the dash out, fix it and re-install and not very expensive either................. all the while feeding you coffee.
Let me know if you want his number
Other than that I can't remember much about my 92 car, other than it was BRILLIANT
