I was in a similar debate, I ended up going with a 2021 LR. Although the Performance model seemed awesome, I knew Tesla was switching over to Tesla Vision so I wanted the latest cameras and computers (they are probably the same but unsure) and the warranty of a new car. Also I live in LA, where am I going to go 0-60 in 3.2 seconds? Not in traffic thats for sure haha, the SR and LR are plenty fast (and I am a sportbike and classic mustang driver as well). It’s also really easy to make your car look similar to a performance with a little amount of money, visually that is (painting calipers, lowering springs, etc). FSD is…well you’ll get mixed reviews, auto pilot is more than enough, I drove a FSD car to Houston from LA and honestly didn’t really use any of the features that auto pilot doesn’t already have. The car changing lanes by itself was honestly too hesitant and unsure, wouldn’t use it ever in traffic, not nearly aggressive enough for drivers out here, you’d never make it over haha. But with auto pilot it does more than enough, stays in the lane and controls the speed and distance.
Entirely up to you though! Just thought I’d throw in my 2 cents! The extra range compared to the SR would be rad though, I’d definitely go check it out, figure out what maintenance would be coming up, check out the body panel gaps and paint condition, etc! Good luck!!
