This is also my concern with marshalls and the £500 cashback also which is stopping me to switch too as it did say place order by December 2023. They no longer have the offer and also the original AP was £4999 and now with m sport its £5999 so additional £1k for the upgrade for us whereas for recent orders its only £500 only
Can you update this forum if you find out from your dealer whether they would honour the cashback and I will chase mine tomorrow too and see what they say.
