99 vehicrosses have 16" wheels and manual a/c controls 2000 and 2001 have 18" wheels and automatic a/c controls... there are rumors of an engine flaw in the 99's that caused a few of them to seize at low mileage... some say that it was fixed in 2001... but nobody has any real proof of either of these claims (there are VXs that have had the engine seize... but they arent all 99's)
