If it's me, I'd replace it. I had a 13-year old car, with pretty low mileage to my standard, I was happy driving it, except that it kept breaking every 2-3 weeks, with leaky hoses and minor stuff, nothing major. But the time it took to repair, we had to take time out, a few hours every couple of weeks, it got old. Dh was the one who took it in actually, and he was so tired of having to go to the repair shop so often, and had no time to do anything else. Not to mention it breaking down while I was driving, sometimes close to home, sometimes pretty far. Time is money. So we replaced it then.
