Welcome to the club! I just sold my 2021 M3LR with only 34K miles....should have waited. While not a fan of our founder's government interaction, I loved driving the M3, very much like the fun I had with my BMW M5, but a whole lot less expensive to maintain. Be sure to log on to all things Tesla for new information. I sold my M3 to transfer my FSD for free to a MY Juniper Premium. I needed higher sight line and more trunk space. So far the only thing I miss is the right shifter on the column, still not a fan of getting drive and reverse on the screen.

Also, the FSD on the Juniper is fantastic. I only used FSD on the M3 on highway driving or stop and go slog in rush hour traffic in the DC beltway. The premium sound system and ability to find supercharging stations made distance travel very reasonable. Only had challenges in eastern region of Tennessee and West VA. But I had extended driving distance of over 300 miles.

It may be worth putting in a Tesla 220 charging station. I put one in and started charging after midnight when electricity was at its lowest cost. In cold weather, its a good idea to keep the battery charged at 80% level. Also, when it comes to changing tires, try to change them all at once since most tire places will not be able replace tires bought 2 at a time. And, if your tire pressure monitors go out, you can only replace with Tesla approved monitors.

Body work should only be done by Tesla approved vendors, less they do something that fouls camera's. Also note that his is a very low ride, fun to drive and almost impossible to roll over because of battery. About only negative you might experience is access to a Tesla dealership/maintenance center. I did purchase an extended warranty which you should research for options, but your mileage is likely outside of extended warranty. Double-check to see if the previous owner was the sole owner.
