Pop the hood and check.

If there is no clutch fan (or massive oversized cowl) and no auxilliary units ahead of the radiator but with just a single electric fan aft of it,
its a '99.

If your spare tire is a black wheel, and not the same as the other 4 alloys on your car,
its a '99.

If your car came equipped with side curtain airbags,
its a '99.

If your radio the same unit used in the 2000 + model 210s,
its a '99.

Lots of clues to confirm the MY.
