2000 Mercury Marquis LS - No ABS or Traction Control

I inherited this car without the ABS or Traction Control Options although it has 4 wheel Disc Brakes.

I am concerned about its safety reliability without these features in terms of handling. I have invested in bringing it up to speed in regard to preventive maintenance.

My question is should I be concerned about the lack of these features or chalk it up to two less items to break and need costly repair?

Do some of you own this car without these features and are content?

Thanks.
