Thanks for all the feedback guys, I'm a lot happier now that I've driven the car quite a bit and to be honest the driftwood has really grown on me. Ironically I was having second thoughts about the chrome after seeing how easy it is to damage (something I, or my kids, would definitely end up doing), so in the end it's probably not as bad as I originally made out.
I was still rather deflated at the time though.
Given that I'd already screwed £7k out of them via Carwow there wasn't a great deal of wiggle room in the deal in the end. But that doesn't make my order right I know.
On the day they immediately gave me the boot liner and bits I'd enquired about to "Make today's experience a little better" and I had a call from the sales rep yesterday but couldn't take it unfortunately. They immediately followed up via email and will call again tomorrow.
I'm thinking Polestar installed FOC will sweeten things sufficiently
Once there's a positive outcome I'll name the dealer.
