That is correct. Since the car has the pre-LCI trunk from the factory, the buyer would need to buy a nice LCI equipped aftermarket trunk and get the LCI kit installed at the same time. I had planned on keeping the car and doing just that until I decided to just order a new M3 this week.
Speaking of which, I got a very reasonable trade-in quote from the dealership so if I don't sell this privately before my new E92 arrives then I'll just trade it in. So if anyone wants this, you've got until my new car arrives
