If you own or are considering buying a 1992 Proton Unclassified, be prepared for above-average maintenance costs. Before your MOT, pay particular attention to lamps, reflectors and electrical equipment: Walk around the car and check every light — headlights (dipped and main beam), side lights, tail lights, brake lights, indicators, hazard lights, reverse light, rear fog light, and number plate lights. Replace any blown bulbs before the test. At 74,507 average miles, these vehicles are in the mid-range where component wear starts to become a factor.

Check the pre-tensioner warning light on the dashboard.
