Underneath, yes. The interior is very different, and imho vastly superior in the 308.
2021 Opel/Vauxhall Astra vs Peugeot 308: Differences & changes compared
For comparison. Of course, we can’t argue preference, but the interior in the 308 is not just better looking (imho), it’s also superior in terms of quality (that silver piece in the 308 is actual metal, not plastic).
That’s where the price difference lies: in the quality of the interior. The Vauxhall felt cheap and looked cheap (we didn’t sit in it, just looked into one when we were at FRF Peugeot which is next to Vauxhall), whereas the 308 rivals a 1series. It’s genuinely impressive.
