First part of the question: over the last ten years is there a certain Forester generation that is better than the other? Engines to avoid or look for? I have very little experience with newer Foresters other than driving them a little here and there. Second question: has anyone used Carvana or know anyone who has? A friend is car shopping and based on her needs, budget and situation she is considering purchasing from them and adding their warranty. She lives in a large city with no family nearby, no local friends with any mechanical ability and her free time is short and valuable.
