are the parts and labor expensive on the land rover discovery II

Just did a quick check at Rockauto.com parts and regular items like filters and brake parts are very cheap. On the other hand wheel bearings are $500 and master cylinders are $200. Labor is always a crap shoot depending on where you take it.

Try http://repairpal.com/ they will give you a repair estimate for parts and labor. The car in question has a reputation of frequent, expensive repairs.
