I have a 3 spoke steering wheel on my 54 plate wrx wagon

I've noticed some have these and some have momo, just wondered if it was a year thing?

 

The wrx changed from four spoke wheel to a three spoke for MY05 cars, also centre console and heater controls, also the seat material was slightly different and the doorcards had material on the arm rests. I also believe the sun visors are different to.

 

Does that mean I must have one of the early facelift cars then?
