Pre-MOT Inspection Checklist for Daewoo Lacetti Owners
These checks follow this Daewoo Lacetti's own most-recorded failure strings, starting with what a tester is most likely to flag on a Daewoo Lacetti.
-
corrosion — “component mounting prescribed areas prescribed area excessively corroded significantly reducing structural strength”
Look under the sills, around the jacking points and where the suspension mounts meet the body. Flaking, holed or crumbly metal fails; a brown stain on sound metal does not.
-
the lights — “registration plate lamp(s) inoperative in the case of multiple lamps or light sources”
Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.
