I recently bought a 1986 560 SEL which has been imported into australia i know not from where, but most likley from japan. The trouble is it has no owners manual or workshop one. The aircon does not work nor the sunroof and the brakes work but the brake pedal bounces now and again when applied hard. the car stops ok but is a worry to me.the merc dealer here can only supply an owners manual for a 1988/89. Would this be suitable for my car?
