This is my 4th Forester, the first one used, the rest bought new. I've had it 12 months and have about 18K miles on it.
Overall, the car is fine but I've had problems with little plastic parts falling off left and right. The inside gas lever, the pegs that are supposed to hold the cargo net (fixed 3x), and on and on. This never happened with any of my older models.
They just replaced a recalled part of the child's seatbelt that retracts into the ceiling. Not twenty minutes after driving off the lot, a piece of plastic fell out of it.
Reliable where it counts. Just big enough for my family with a 9 year old and 2 dogs.
Well, try making the interior parts stay put for starters. After that, stronger metal on the outside (it would ding if you threw a marshmallow at it), and less road noise.
