Timing Chain is made with plastic parts?
A local repair shop (not dealer) has been handling the routine maintenance on my 2010 Mini Cooper S Clubman. They recently warned me that the timing chain should be reworked/replaced as the vehicle now has 77,000 miles and the factory parts are partially plastic and are deteriorating. Estimate was for around $1,500 - $2,000. Does this sound correct, or are they trying to push me to do something not needed?
