AWD. Drive it home. It either has a bad motor mount or possibly a rod noise or something else. Noise noticeable at low idle but not while driving. Needs a exhaust gasket at catalytic converter. Trans. slips sometimes at about 50mph. I haven't dropped pan to check filter, etc. Engine miss on occasion. Tires have low miles, catalytic converter and battery replaced a few miles back, new struts, right axle joint and a few other things. We've owned it 20 years. Clear title.
