I own an Mg ZR and have had it since new from August 2004. Just when it achieved 20000 miles the exhaust went. Can anyone advise the life expectancy of these original exhausts . The garage I purchased it from has closed and am trying to recover the replacement costs from Capital Bank ( financers). The problem is no face to face discussion. My wife has a 5 year old Rover 25 which has had no exhaust problems. The Capital bank says exhaust went under "fair wear and tear". Anyone else had a similar problem.
