I dunno, for me that P looks perfect. It's like the ultimate classic Model 3. It's got everything. FSD adds 8K value, and IMHO it whips the llama's ass right now, but watch the next few months. I would imagine the owner took very good care of it. Just get some of that New Car Smell spray for day one.
So I bought a used 2018 M3P, back in March, with 10k miles for $53k + TTL.. which came with EAP. I then sprung an extra $4k to get the FSD upgrade before the price hike. You can get the same with FSD for $52K, but with an extra 10k miles. I have full faith that the upcoming AP rewrite is going to be a game changer and will increase the value of all Model 3's that have FSD by a good amount. If I were in your shoes, and knowing what we all know now, I'd start with the used 2018 M3P with FSD and wait for rewrite update. You could then sell that car for probably the same amount, if not slightly more, and then buy a newer LR AWD with all the latest updates. Warning, if you are a fan of performance vehicles it will be very hard to go from a performance model to anything less. I've beaten 2 lambos, a newer NSX, and a slew of corvettes in my M3P. You won't get that with an AWD LR, even with the performance boost. Not to say it's a slouch, but the extra umph you get with the M3P is exquisite!
