Red July 2018 build. Still looks great. No ceramic or PPF. Keep it washed (me or the touchless place down the street) and waxed (the inexpensive, easy to use spray on/wipe off kind). Always parked in a garage when at home and under covered parking, if available, when travelling. Took a hit last year to the driver's door from road debris that exposed bare metal (doors are aluminium so not worried about rust). Used touch up paint from Tesla and it looks almost like new (only I really notice it).
IMHO the key is to limit sun exposure. Red cars I have owned in the past suffered significant damage from sun exposure, so I avoid it when practical. And if I lived in a place where the sun always shines and temps in the 90s or higher are common, I would probably avoid the red.
