Colour co-ordinated sills, new body kit, updated front spoiler, moved the boot lock next to the boot handle so no longer visible, new wheels style option, but nothing profound from memory that I can think of. Otherwise layout and interior remain the same. Obviously some cars were spec'd differently from standard such as heated leather seats, or heated electric leather seats, CD multi-change, but that was all covered in the options list at point of purchase. That said these updates may have happened in 2000-2001 rather than 1999-2000.
