From your list of must haves
mud flaps can be retro fitted , not sure of cost for factory fitment? Assume negligible
wish list
Two tone paint can be done at a later date, although IMO a lot of work for a body shop cost for retro iro £1500- £3000, if you want it get it factory sprayed
led lights a high cost but IMO literally light and day between standard H4’s or even H7s. The LED lights are amazing if you drive at night. Get the auto lights option.
I have everything on your list except colour / digital cockpit, with the exception of the VW fridge, which I believe is a cool box rather than fridge ?
storage compartment pack - don’t know what this is
bike rack, ask the dealer to include in The sale / order deal ? Or add it later ( same cost as it’s dealer fitted, not factory )
My Beach was an ex demo as has just about every extra you could have specked, if I bought a beach again, I would have everything on your list .
if you intend to keep the Cali, get it exactly as you want it, it’s a severe amount of money, have it right and as you want it. Obvs if you have a tight budget prioritise.
