Your thermostat is probably stuck open. They are cheap and easy to change.

Coolant temperature sensor. $40/$50 part at your local auto shop. If you want to check your thermostat, just boil it and see if it opens up.

Why bother. If you're pulling it out anyway, just replace it. They're like $10

If the coolant temperature sensor didn't work, the gauge may read wrong, but the coolant would still get hot if the thermostat is functioning properly.

Got a point.

You just got it so you should be doing a full tuneup anyways. Belts, fluids, thermostat, etc.

Wait... What?
it should warm up once you replace the thermostat, if not then the heater core could be bad. I don't know where you're located but driving in cold weather will keep the engine below the middle of the gauge because the radiator is taking in that cold air constantly.
