both the escape and the forester have a ground clearance of 200mm
on parts support you have Ford Phils and MotorImage (s.e. asia & china dealer for Subaru) to run to.
on price of parts always go for oem to protect your investment, unless you want racing parts of w/c there's none for Escape (i still have to see an Escape on the track). For the Forester you can upgrade it to an STI version, if you'll get the 2.5XT
on mechanics, if its a regular maintenance like oil change, brakes, other fluids. there's lot to choose for both brands, better yet get your own manual from Hayne's and the like. If it's a tune up go to the casa or performance shops.
