Mitsubishi Lancer 2008 Rear Sub Frame Fault

Car has been mechanically very good and was in daily use up until an NCT failure for rust on the rear subframe. See NCT report attached. While the car has a few dents, it is in good shape with a major overhaul 2 years ago when a new second hand engine was fitted with water pump and fanbelt being replaced when we had the opportunity. Although not rerquired, a new clutch kit was also fitted. Car has tow bar fitted and wired. I know the sub frame could be repaired and the car would have many more miles in it. It would be a shame to break it , but if no reasonable offer it will go to the breakers.
