So I do plan on switching to better tires when the time comes.
That was the main car I wanted to get but, my dealer didnt have what I wanted and was like hmm might as well test drive the focus when I was still there, sure as
I liked that more/came home with it - drove better, more space, ect. Just all around more car for the $
Def doing the lightweight wheels and LLR tires when the all seasons wear out then replace them with snows.
Not sure about the oil but I will be adding a new drop in filter for now.
