This was at the end of 2021 or beginning of 2022, so the Mk8 wasn't out yet. Mk 8 models are also a bit more expensive, so the discrepancy would be a bit better in that case, I would imagine. Out of curiosity, are the Mk8s not too well received, or are Mk7s preferred?
I don't mind the change, but my current car works and I might as well hold out for an EV like Cupra Born or Peugeot e-208 personally.
