Thanks! This is what I was thinking. The plugs have been done already, tires were replaced at 90k miles, brakes done at 70k miles, the only thing I'm unsure of is whether or not the transmission has been serviced. I didn't notice anything too unusual in the test drive. The rear backup camera needs to be replaced and the blend door actuator on the passenger side has a little clicking problem but still blows hot and cold., but I can replace both of those myself for probably $100.
