The head-up display was first available on the 1999 C5 - I know, as I ordered this option when I purchased by 1999 C5.
The active handling and traction control first became available as a mid-year, 1998 model option. It was available as an option on the full model year 1999 C5, and later became standard.
Gents, I stand corrected. Thanks
