It’s not the rarest of colours for them, since there is also a jasper avant on eBay that’s been on there for a year now since being snapped up for a measly £1750, but not as common as silver or nogaro
I have one of the rarer ones just now, kingfisher blue, but is now basically a shell due to breaking it to buy a house, kingfisher and Merlin purple have to be the rarest of the colours for them and the only 2 colours I’d consider if I buy another
As for the interior, a cloth interior isn’t unusual and I’ve seen plenty with cloth, some standard style seats and some recaros, recaros being a lot rarer due to being a costly option at build time, I’ve also seen a few without the carbon trim but the majority had them although the gear surround was an optional extra too so not so many have that
I have a bit of experience with the S4’s having had 2 now and I don’t see any issue with that car other than the rusty wings and being listed as a facelift where it’s a part facelift/midlift with the pfl rear bumper and analogue clock on the dials
I’d be amazed if it goes for a penny less than £3k! If you’re looking for a S4 for £2k then you’re around 12-18 months too late, prices have soared both for whole cars and parts
