Just bought a 90Qs 20V with a "few" issues.

[Richard J Lebens]

There is a 20V specific mail list but there are fewer and fewer members
as time goes on for reasons mentioned below (12) in your questions and
expense of maintaining these cars.

Most likely the Multi Function Temperature Switch.  About $90 and lasts
for 2 years.  Ignore the gage, it it is redundant.

I think you are describing the covers that go over the screws that hold
the bumper on, two 6" long screws with hex sockets?  Removing the
bumper is a common maintenance routine.  As to where to get those body
colored covers best find a junkyard and get lucky

WTF???  Plenty of ways to play with the torsen differential without
being stupid.

Time to get dirty and crawl under the car

You have the center console gage option.  Mine varies with RPM so I
would guess the sender is failing.

Sure this doesn't go to the air filter?  (also major PITA)

Hitachi injectors good?  $250 each  (may be Bosch hack replacement)

Crankcase oil vent update installed?

Plastic distributor gear death rattle on decell?

Rubber side moldings ($$$$$) peeling?

$150 front brake rotors due to factories random selection of brakes?

Hole in exhaust where the hangers fail and it rubs on the drive shaft?
