I've owned this Z5 around 9 years serviced between 9000-10000 miles always got oil, oil filter, fuel filter, air filter, 18" wheels, absolutely brilliant motor. Has pulled a light weight trailer with a couple of lawnmower's in it. No heavy work. A few small age related marks, only being used once a week now and a reluctant sale. Absolutely bulletproof motor. All very good tyre, two new front discs and pads.
