I wouldnt call a 535i sport a base model...Originally Posted by vuyodaddy
A lot of UK spec 535i sports were shipped badged as M's from the factory - in fact the first E34 I ever had the pleasure of driving/working on was an M535i.
It appears they were special editions or something, as they were shipped with sports suspension, Mtech lights all round, Mtech steering wheel, Mtech shifter and handbrake parts, Red Clocks and cloth sports seats (upgrade to leather avail.)
Sadly they're quite rare these days.
