yo so i actually talked to a shop about a similar project recently and ngl, i would be SUPER careful about touching anything near that screen. like seriously, one wrong move with the wiring or even the weight of a new panel can mess with the sensors. since you wanna go custom, here's how i'd break it down from a technical standpoint:

* **Option A: Mansory Bespoke Interior Program** - these guys are basically the kings of "too much is never enough." they do the crazy forged carbon with gold leaf you mentioned and their leather work is top tier. pros: they have the most experience with ultra-high-end EVs. cons: they're in germany, so shipping a celestiq back and forth is a literal nightmare and expensive af.
* **Option B: Galpin Auto Sports Custom Interiors** - right here in the states. they're legit experts at tech integration and could probably handle the watch winder setup without bricking your software. pros: easier to oversee the build. cons: might not have that specific "european boutique" feel for the exotic woods unless you source them yourself.

anyway i'd definitely suggest a professional consultation with an electrical engineer before you let anyone pull the dash apart... those 55-inch displays are fragile and honestly irreplaceable right now if they crack. gl with the build tho!

So i actually tried a custom carbon dash on my last EV and it literally triggered a persistent airbag fault code cuz of the added weight... Unfortunately, it was a total nightmare to fix. Seconding the warnings about that screen!!

1. Carlex Design Bespoke Interior: Best for gold/wood but can block thermal sensors.
2. Alcantara Bespoke Program: Much lighter and safer for dash panels, tho less flashy.

Basically, dont mess with sensor placement or ur gonna regret it lol.

In my experience, when you're dealing with a car that's basically a hand-built sculpture like the Celestiq, the aftermarket world is kinda still catching up. Honestly, finding a shop that won't brick that 55-inch screen is the real challenge. I've been looking into similar one-of-one vibes for my setup and it's tough out there!!

I think... and don't quote me on this lol... but I heard some guys in high-end EV circles mentioning that [[Mansory]] might be looking at the Cadillac platform since it's basically the American Rolls now. I'm not 100% sure if they have a dedicated program yet, but they're usually the ones doing that forged carbon infused with gold leaf stuff you mentioned. If you want that specific look, those are definately the guys to call.

For the watch winders and specialty woods, I'd actually suggest looking at boutique yacht interior designers. I mean, seriously, they're used to working with crazy hardwoods and tight integrated spaces. Just keep in mind that custom work like that is gonna cost a fortune and might mess with ur warranty if they tap into the electrical for the winders. Plus, that massive screen is tied into basically everything, so if a shop isnt careful, it's a nightmare. Personally, I'm pretty satisfied with the factory options cuz they're already so high-level, but if you really wanna go bespoke, maybe check out [[Vilner Garage]]? They do some wild interior overhauls. Just my two cents... honestly just be careful with the tech!! gl with the build!!

tbh i had issues with boutique shops overcharging for poor fitment lately. Are you looking for a total teardown or just accents? most high-end brands just aren't worth the premium honestly...

@Reply #6 - good point! Seriously, the parasitic draw on a high-voltage system can be a total nightmare to troubleshoot if the car thinks theres a grounding fault. Saw this thread earlier but just getting back to it... Basically, everyone here is spot on about the 55-inch screen being the danger zone. GMs technical architecture is super sensitive to thermal changes too, so blocking any integrated vents with thick wood panels is a no-go. If youre dead set on that gold-infused carbon, check out Carbon Fiber Composites Gold Weave Panels. Ive been happy with how these handle signal interference compared to cheaper alloys. For the silk mats, Id actually look into Prestige Custom Carpets Silk Blend. They use a tighter weave that wont shed into the seat tracks and jam things up over time. Just make sure whoever does the install uses a dedicated 12V buck converter like the Victron Energy Orion-Tr DC-DC Converter for those winders to keep the signal noise off the main bus. Works well for me in long-term setups without triggering any annoying ECU warnings lol.

Re: "In my experience, when you're dealing with a..." - ugh i am honestly in the exact same boat and it has been so frustrating trying to find anything legit. I have been looking into this for like three months now because i really wanted to swap out some of the heavier interior bits for performance-grade materials to maybe get a bit more agility out of the car, but unfortunately nobody seems to know how to handle the tech. I had such high hopes for some of the boutique shops i contacted but they all basically ghosted me once they saw the specs for that 55-inch screen... it is seriously disappointing. Ngl it feels like we are just stuck with the factory configuration for the foreseeable future because the risk of bricking the electronics is just too high for these guys. Still haven't found a single shop that actually gives me confidence, which sucks when you want that true one-of-one feel.

This^ also wanted to add a bit of a reality check from someone who's spent way too much on interior mods over the years. Honestly, I totally agree with the warnings about that massive screen—GM basically built the car around it, so messing with the dash is high-key risky.

If you're looking for a more cost-effective way to get that custom vibe without the risk of 'bricking' your tech, here is how I'd play it:

1. Stick to 'soft' touchpoints: Focus on the floor and seating. I've seen some incredible work from boutique shops using Moore & Giles Luxury Leather hides or custom silk-blend carpeting that doesn't require pulling apart the electronics.
2. Removable console inserts: Instead of permanent watch winders, maybe look into a custom-fitted housing for a Wolf Viceroy Single Watch Winder that can sit securely in the rear console without hard-wiring into the car's main bus.
3. Magnetic trim overlays: Some high-end shops can CNC thin wood or carbon veneers that snap over existing trim. It’s way cheaper than a full replacement and totally reversible.

Basically, I've learned the hard way that 'one-of-one' can quickly turn into 'one-big-headache' if you touch the wiring on these new EVs. Keeping it to bespoke materials rather than structural changes is the move imo. gl with the build!

I was reading through this earlier and honestly, i gotta ask... are you planning to hardwire those watch winders into the cars accessory power or go with a separate battery pack? id be really careful about how you interface with the electrical system since these high-end EVs are super sensitive to parasitic draw or any signal noise on the bus. Just a couple technical tips if you're looking at bespoke stuff:

• If you go with the sheepskin mats, make sure the backing is compatible with the floor sensors. Maybe check out Lloyd Mats Luxe Custom Floor Mats for a base template if you're going full custom.
• For the console storage, definitely use a Fluke 115 Digital Multimeter to map out your power points before you let anyone start cutting. Basically, you just gotta make sure any new metal or carbon doesn't act as a shield for the interior wireless antennas... that would be a nightmare for your connectivity.
