What makes it obvious? The Mk8 R Line is about £600 more than the outgoing model in R Line Edition trim.
I’m going based on what a 7.5 listed at close, which was circa £33-34k basic. + New model, inflation, WLTP excesses, it’s all going to add up to circa £35k min IMO.
If VW offer a manual then yes it’ll be a slightly cheaper asking price, but I think if people are expecting a £30k price they are going to be disappointed, that is unless VW make lots of standard 7.5 kit, optional on the 8.
