Difference between these car seats!?

[Hotchoccie13]

Please can someone tell me that the difference is between these 3 car seats? I literally cannot find anything different about them!?

Britax AdvansaFix
Britax VersaFix
Britax EvolvaFix

Thank you 🙏x

Versafix and Evolvafix are identical except that Versafix has stitching on the cover whereas Evolvafix does not. (Why this justifies an entirely different name? 🤷‍♀️🤷‍♀️🤷‍♀️)

Advansafix is the more "premium" version so has a few more features e.g. it has the XP-Pad when it's used in high back booster mode, the padding is a bit more ergonomic, it has extra side impact protection.

They are all the same shell and are very similar seats.
