I am not trying to discourage anyone from doing mods. But there (there's always a but), think it through. Here's why I say this, and tell me you don't think this would apply to a mod like a steering wheel swap.
About a year and half ago, I was talking to an owner that was complaining about how Tesla changed the trade-in value he first had to an adjusted second offering. First he got a trade-in quote for his car from Tesla online and confirmed it over the phone I think he said he was talking to someone in CA. He was told to take it to the store for someone to put eyes on it. He was just about to put his down payment down and was at the store. After seeing his, the Tesla person designated to review trade-ins told him they knocked $4,000 off the trade in because he had taken the OEM wheels off and had other 21's on it. He was shocked. He had sold his OEMs and didn't have them to put back on. The explanation he got was that Tesla was going to put OEM wheels and tires on it to sell it. They would not sell it with the non-OEMs and would not warranty them. He said that $4,000 lower trade-in offering was a deal breaker for him. This was back when there was an official CPO program. Maybe it doesn't apply today. I don't know, but I do consider it.
I doubt Tesla would charge $4,000 against that car to put new Tesla wheels on it, but that's what he said. Every mod I have made to my S's can be undone and put back like it did when I took delivery.
I remember reading on TMC that an owner was told that they reduced his trade-in offer because he had a Blackvue in his car. Most people replied just remove it and save time by hiding the wires. I think he said he would .
Consider that you could take a hit on the trade-in value to Tesla if it doesn't look like factory when you want to move up to a newer one. Maybe it won't matter, but you might find you have to find a private buyer so you don't have to un-do what you did.
That white/carbon fiber steering wheel is definitely cool. But did you have to give your original one with that purchase? Why would the seller do that? Would the be doing this to make it hard for you to put the original back on and trying to sell your used white/carbon fiber on eBay and competing with them?
