I'm a big advocate for Burmester and had it in previous P-cars. In the case of the Taycan, get the full leather and BOSE. In my 22+ years in the OE and aftermarket automotive building and enthusiast arenas, this is the best BOSE installed in a Porsche.
Worth it to me - thicker grips are a must IMO. I drove a loaner 4S for a while without chrono/GT wheel and did not care for it.
In the near future I'm having Exclusive Option make me a deviated stitching wheel with their even more increased thickness.
As most have experienced, including myself, they console charger rapidly heats up the phone to the point where it overheats.
OP: what's wrong with putting the phone in the cupholder? I do when I'm charging via the rear seat ports. If not charging - phone stays in my pockets. (carplay)
No black interior. (2-tone colors are gorgeous)
No black designation. (why pay for black emblems - cleaner look w/o emblem)
Sport side skirts are a waste of $ IMO. All you get is a small painted inlay.
Get crest on all 4 headrests - looks half-ass with only 2.
Rear 2+1 seat is a joke.
