Welcome Anthony! B) Congrats on your 'new' ES. The wind noise around the frameless windows can be an occasional issue, but not major.
The only other major concern is the possibility of engine gelling (do a search in this forum & you will find much more info).....however, the good news is you said you know the previous owner & that they had the car regularly serviced at the dealership.
Consider switching to synthetic oil is my best suggestion for that engine & make sure oil changes are done on time, everytime. B)
