Long time fan first time owner

Hello to all I have recently come to own a 02 Infiniti g20 I brought it very cheap and my intention for it was to just drive it till the wheels come off. But in doing this I have come to love this car. So my question to the group or those who have experience with these cars specially. What are some of the things I can do as preventive maintenance to maintain the life of this car besides keep up on oil change It has 196xxx miles on it. And i drive roughly 75 miles a day. I appreciate any advice thank you all in advance.
