Ill be looking to buy a 2004 Mazda 3 hatchback 5 spd with 194k miles. Needs passenger front hub assembly, minor rust, and a wobble at 70+ mph. My main concern is the higher mileage and from what Ive read online the timing chain doesnt need to be changed. But would it need to be done at that mileage? Anything to look for in particular when I check it out?
