The 525 loses some luxury items from its standard equipment list; the steering wheel is now wrapped in leatherette instead of leather and the spare tire is shod with a steel wheel instead of an alloy. The 535 gains options like a nifty on-board computer and a power-adjustable steering wheel with a position memory. A security system is now standard. The M5 gets better power steering and a higher final-drive ratio. A Touring model is introduced as a wagon body style.
