I have a 2006 Subaru Forester with 104,000 miles. I need a new clutch - it is getting very hard to shift - and should replace the timing belt and do the 105,000 mile maintenance. Also need brake work and will need to replace the tires soon. There is also now a screeching sound (a belt?) whenever I turn the AC on. About how much will all of this cost, and is it worth it, or should we just look at trading her in on a new Suby?
