Undriving car

What is your question?

Hi guys, I have a car, but I never drive it. Coz I can commute with the train to go to work and also driving my wife's car. I'm planning to buy my car insurance and put PNO for DMV registration since I dont drive my car anymore coz I dont want to sell my car. My question is, Is that OK for accord 98 if I dont drive it for a year? I just park it at home, but I keep warming the engine once a week without drive it at all. Thank you very much
