I've been looking at purchasing an Outback and pondering the decision of what years to look at. I can get a high mileage (150k) Gen 4 for the same price as a moderate mileage (70-100k) Gen 3. I've owned Subaru's and presently own but new to following the Outback. I'm looking for manual transmission cars only and I'm not interested in getting an XT or anything. Is there any key differences between a Gen 3 and a Gen 4 to consider? What would you buy? Curious to read all you responses!
