i’d also do fuel filter, plugs and wires, coolant and hose change, brake fluid drain and bleed, maybe drive belts for alternator etc unless you know when those were done. these are the main items that will strand you, cost more if ignored, or compromise safety.
what condition are struts in? this is a HUGE expense, even for the DIYer….like over $300 just for the parts, assuming nothing but the struts needs to be replaced.
my 2002 eats regular gas just fine, even with lead foot and hot west Tx summers.
no exotic plug requirment. various people have their preferences; see other threads on this. NGK, Bosch, and Nippondenso all genlly good plugs.
welcome to the board! i don’t disagree with Karl, but he’s talking from a dealer’s point of view. in terms of seat of the pants driving experience with an 80-100K mile car, you won’t notice THAT huge a difference between OB and Legacy. get the OB if you need the height or ground clearance; otherwise, you’re correct that same $ will get you a newer Legacy
