Just taken delivery of a '91 730SEi with 137k. - I've got no owners manual, don't need a service manual but need to know how things work (computer, heater buttons etc). Is a web copy available? - I'm not sure if this model has an alarm/immobiliser? - Should it have remote central locking (I only have std door keys). - Is the rear screen heater the radio arial as the reception is extremely poor. - The service book has a different engine no than the registration doc. I assume a racement has been fitted. Are there any obvious signs to tell? - The car has some slight steering shake at certain speeds (could just be wheel balancing) and occasional shake under braking. Is this likely to be the front bushes?
