1998 BMW Z3 3.2L Petrol · R780 APU

The most recent MOT, dated 11 September 2024, was a pass, although it retained the advisory notes concerning corrosion of both front suspension arms. Over the last three years the vehicle has alternated between pass and fail results: a windscreen washer failure in August 2023, a major ABS warning lamp fault and a faulty off‑side position lamp in September 2024, each subsequently rectified before the next test. This pattern indicates that while the car’s overall maintenance has been reactive rather than proactive, the current state appears stable provided the identified faults have been properly repaired and the corrosion advisories are monitored. At 75 358 miles on a 1998 model the average annual mileage works out to roughly 2 700 miles per year, which is considerably below the typical usage for a vehicle of this age. Such low utilisation often points to periods of infrequent use or extended storage, both of which can accelerate age‑related degradation of rubber and polymer components, promote surface rust, and allow battery electrolyte to deteriorate. The modest mileage does not, however, eliminate wear on high‑stress items such as the clutch, gearbox bearings, and suspension bushings, which are more dependent on the number of load cycles than on distance travelled. Potential buyers should give particular attention to the front suspension arms that have been flagged for corrosion. Visually inspect the arm tubes for any pitting, flaking or loss of material, and feel for excessive play in the ball joints and bushings by applying a firm push‑pull at the wheel while the car is lifted. During a test drive listen for clunking or creaking when negotiating bumps or cornering, and check the tyre wear pattern for signs of uneven loading that could indicate compromised geometry. Verify that the ABS warning lamp remains extinguished after a short stop‑and‑go run, and confirm the operation of the off‑side position lamp; a fault in either system could be symptomatic of wiring corrosion or sensor failure that may re‑appear if not fully addressed. The windscreen washer system, though previously failed, should be tested for proper spray and pump operation, as a non‑functional washer can be a safety issue in wet conditions. Given the car’s age and low mileage, a thorough age‑related inspection is essential. Examine all tyre sidewalls for cracking, hardening or loss of tread depth; even if the tread is adequate, rubber can perish after a decade regardless of use. Check the 12‑volt battery for voltage under load and inspect the terminals for corrosion, as prolonged standing can lead to sulphation and reduced cranking power. Inspect brake discs for surface rust, scoring or uneven thickness, and ensure the calipers move freely without binding, especially since the ABS system has previously flagged a fault. Finally, confirm that the engine oil, coolant, brake fluid and steering rack fluid have been changed in line with calendar intervals rather than mileage, as fluid degradation over time can cause seal wear, overheating and reduced braking efficiency. A complete service history and receipts for recent component replacements will provide additional confidence in the vehicle’s long‑term reliability.
