My Mirage is my second vehicle, next to an SUV family hauler. I don't really need it, but I do use it often to save on gas (about 10k miles per year).

It is a 2015 ES manual with 87,500 miles. Carmax is offering $6000 for it.

My wife's car is a 2013 Elantra with 168,000 miles and an infamous engine. I see the the Mirage as an emergency back-up if her car dies so we can wait till the car market improves. We could use the money as I am retiring early. I just wonder if it has more value keeping than selling for cash. What would you do?

It will need tires soon. Just replaced battery and plugs. Front and rear brakes were done 15k miles ago. I do live near Chicago and rust is rearing it's ugly head.
