I bought a 1996 320 coope in January (110k mls) and I now have a problem with the 5 speed auto. It will not change into 5th and when i approach a junction/roundabout it may stall . Any thoughts and who can i contact locally (Salisbury/Shaftesbury)? I appreciate that i may have to go to Mercedes Salisbury, but I am fearful it may result in a new box from MB costing more than I paid for the car!!! Thanks, Adam (ac@pcse.co.uk
