Repair estimates are a guide for an independent garage: labour at the national median local garage rate (median £78 an hour from 65 garages, ONS price quotes) times estimated labour hours, plus a parts band. Labour hours and most parts bands are estimates, not quotes, and prices vary by model, engine and region. A warning light fault shows the cost of the diagnosis only.

What to check on a viewing
On the Isuzu Rodeo, testers most often record side/position light not working; headlamp aim: projected beam image is obviously incorrect; rear fog lamp: not working. Look at these first, then the areas below.
Lights and electrics
- With someone outside, try every light: dipped and main beam, indicators, brake lights, fog lights and number plate lamps.
- Check that the warning lights come on with the ignition and go out once the engine runs.
- Look for misted, cracked or yellowed headlamp lenses.
Suspension
- Listen for knocks or clonks over speed bumps and rough roads on the test drive.
- Push down hard on each corner: the car should settle at once rather than keep bouncing.
- Look behind the wheels for broken or heavily rusted coil springs and split rubber bushes.
- Check that the car sits level and that no tyre is worn on one edge only.
Brakes
- On the test drive the car should stop in a straight line without pulling, juddering or grinding.
- Look at the discs through the wheels for a deep lip, heavy rust or scoring.
- Check that the handbrake or electronic parking brake holds the car on a slope.
- Ask when the pads, discs and brake fluid were last changed, and for the receipts.
Ask for the car's MOT history and service record: advisories that repeat from one year to the next show what has been left. GOV.UK MOT history.
