I see nothing in your post that indicates you need awd. I humbly disagree with those who say it needs special maintenance. Being awd with more drive train components, it needs slightly additional maintenance as far as lubrication is concerned. Other then that, treat it like any well maintained fwd car. The Subarus and other awd cars cost me NO more to maintain then my fwd cars other then gas mileage and the cost of extra lube in a transfer case. BTW, they cost me much less, not more, in tires !
My biggest concern in buying ANY awd car USED, would be how it is driven. They are often asked by inconsiderate owners to do things more then they are capable because of their added traction. Abusive teen drivers like my neighbors great but fun loving kids, would not give me confidence in looking for an awd car for $5k. I know people who drive Subarus sanely that get 200k easily from them. so great experiences are often from original owners. You never know.
Racing across an ice covered lake, doing spin outs and crashing into snow banks then trying to pull dad’s 3 quarter ton plow truck out of a ditch with a rope tied to a suspension component, does not make for a reliable vehicle used. These kids do this stuff with awd cars !
IMHO, if you don’t need awd, don’t buy awd for other reasons. I would look at non awd Honda, Toyota, Fords etc. and others for reliability and needs when buying used. If Subaru made a 2wd car, I would include it…they don’t, other then their delicious sports car.
