Nothing.
This car is extremely safe and comfortable.
It was a bit too slow for Germany (only about 165 km/h maximum).
The best was the braking system (4 dual-disk, anti-lock brakes with hydraulic - not vacuum - booster).
I have a 1978 lincoln mark v cartier edition and it is hands
down the best car ever made. nothing ever goes wrong with it.
If ford made a car like this now they would not only bury gm, but they would bury japan also. fix or repair daily, i don't think so!!!
I know, lincolns of the late seventies are THE best cars ever made. when I see the junk we have to drive around in now (hondas that destroy the motor when the timing belt goes) i shudder. new cars are corporate, throw away crap!!!
