A year is too long to go for a car that needs to be reliable and safe. Have it serviced at least every 6 months. Someone needs to open the hood and look around, inspect the tires, check the fluid levels, test the battery etc.
A lot can happen in a year. Tires can lose air, a coolant hose can start leaking. A rodent can nest in the air filter. The power steering pump may start leaking. Unless you are doing this yourself every month or so take the car in and have it serviced. At your age you deserve the very best!
