Build sticker

[Dazines]

Hello,

This is my first post so please be gentle!

I've just inherited my in-laws 2002 Sport and I was trying to confirm that it is definitely the 100hp model. I have the original bill of sale which indeed says 1.4 100hp plus it has the 16V badge on the back and the red line is at 6500.

Here is where it gets a bit strange...

The build sticker in the boot says the engine code is BBZ which I believe is the 100hp one, BUT the number where it is supposed to say the output says 74

Has anyone ever come across this before?

Pic attached.

Cheers!
