I don't think you have ever change the oil on your car! I have never once jacked my car up to change the oil, even my 1985 pontiac fiero I was able to reach the drain plug from the side. My current veloster I can do from the front same with my wife's journey. All you need is a low profile pan.
For me its not about saving the money it's about saving time, I can change my oil in less than 30min and I don't have to drive anywhere and wait. Also I hate the high pressure sales every time you go to those lube stores.
