Right enough Kiera (sorry if I've made a mess of your name) the blue GT looks like your Avenger.
I don't know if the early style wing badges were the same dimension of the rear badges and I'd guess they (the wing) badges fell off or were dinged off in a bump.
What you could do is take the small Avenger badge that was fitted to the grille, I mean the square grille badge, and put one on the wing with the 'A' about lining up with the wheel rim. If someone esp. has an early Avenger grille badge missing its pin this would be about ideal with a bit of sticky plastic for wing jewellery. I'm not going to do this on mine until it gets the last coat of paint and P2000'd.
Somewhere about here, or maybe further back



Same size as the script on the round grille badge. Why were the later grille badges circular, twin downpipes?

And new roof gutter trims - not cheap!

The tail lights pattern on a Xsara look a bit like...

The PSA thing where there are two 5W tail lights per side.
