I have been helping my aunt look for a car she decided on a 2007 Pontiac G6 with the 3.5 v6 104k on it, original owners, they claimed to have kept up with the maintenance, looks like they have but...... It has new shocks, struts, front end alignment, seems to be a decent car it had a few inactive codes for emissions but runs great. I'm gonna maintain the vehicle for her just like her old one, I wanna do plugs, wires, trans oil and filter. Is there anything else I should be looking at doing preventive maintenance wise or anything else i should be keep an eye out for?
