Good day everyone

I own a 2009 4 door Honda Civic with 57,000 miles.
I know nothing of cars. It's in fantastic no problems shape. In January of 2023 I will have $4000 to play with. Now I'm going to try and spend as little as possible on the vehicle but I also want to do any maintenance that I should have done.
I keep up with oil changes quite often.
What are some things I could do to ensure long life?

Thank you for any suggestions. I want to keep this vehicle in awesome shape.

 

Tires, battery, brakes, and fluids. Assuming none of that has been maintained along the way.

Professional detail and a ceramic coating would go a long way towards preserving the exterior.

 

Early 2009s were also victims of the cracked engine block, check your VIN.

 

I’d do a transmission fluid change, coolant fluid change, and an alignment first, then see if other parts are damaged or worn out next.
