I’m about to pull the trigger on a 2024 MX Gen2, and I’m researching the options. I believe I can add Enhanced Autopilot and FSD after purchase. Is that true? If so, is the upgrade purely OTA software, or are hardware changes needed? I’m aiming to stay under $85K to get the $7,500 discount. Here's the build I’m considering: Stealth Grey, 20" Cyberstream wheels, All-Black Premium interior, Five seats, Tow Package, and Basic Autopilot, but I’m wondering about upgrading to Enhanced and FSD later. Any advice?
