I wonder of there are any other changes to the facelift model?
Bumper was different for sure, but what about interior?
The wiring for the headlamp bulbs is different so look out for custom wiring for the headlamp. Facelift had two separate bulbs whereas preface lift had 1, an h4 to be precise.
Thing is with h4 when you high beam you also switch off the low beam whereas with the facelift when you high beam the low beam stays on.

Could have been a late registration, no harm in that, but I think the manufacture year/model year is in the chassis number.
Usually 9th or 10th digit in modern cars but my land rover has the model year code JA in it which means 92, nice and simple cos its a J reg.
Perhaps post up the chassis number
