I bought a 2010 diesel forester 18mths ago 120k on the clock.... ok for 15mths & 7k miles then crank rear oil seal went. This was due to a wobbly crank shaft found after dropping the gearbox for the second time. It now has a 2012 52k outback engine awaiting an exchange turbo! ££££.
Save money by spending a bit more by going for a late 2011 or 2012 car. Oh apparently crank problems 2008-10 can be due to weakness in the bearing web design. Also Legacys and Outbacks are not so affected??? Or so I've been told...
