Indeed, very sorry for your loss.
My car was owned by an "older" lady, it was 2yrs old and had done 1500mls. I treated it as though it was almost new and gave it a belated break-in. I doubt it had ever been revved beyond 3000rpm (if that), and with some progressively harder use it has definitely improved. I used the manual/S mode to hold it in lower ratios.
