What fails a 2006 GS300
Everything a tester recorded on this vehicle, grouped into the inspection sections that produced it. The notch on each bar is the national share, so you can see at a glance whether this car is unusual or just ordinary.
A test can record several items, so these percentages do not add up to 100%. The exact strings, with prices, are in the full DVSA record at the bottom of this page.
Before your test
Three checks worth doing on a 2006 GS300
These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.
-
Check the lights 3.9% of tests
“headlamp lens slightly defective”
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.
-
Check the windscreen 3.7% of tests
“windscreen damaged”
Check the driver’s side of the screen within the swept area for chips and cracks; anything larger than 10mm in the driver’s central view is a fail. Most chips can be resin-repaired for far less than a new screen.
-
Check the shock absorbers 3.0% of tests
“shock absorbers has a serious fluid leak”
Press down hard on each corner of the car and let go. It should settle in one bounce; if it keeps rocking, or you can see oil weeping down a shock absorber, that is the fault a tester will find.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
