Tesla Club Sweden

I'm getting a Model Y Performance soon and want to trade-in or sell my current Deep Blue Metallic 2021 Model Y LR (1400 Swedish Miles) at or a bit after pickup. I have upgraded the current 2021 MLR with enhanced autopilot and acceleration boost and if I understand correctly Tesla wipes that after taking it and likely won't increase my trade-in value, but would those upgrades increase it for a reseller? If yes, which should I contact?

I like kvd.se (auction with minimum price).
