About This Data

The 1968 Jaguar 420 has an MOT pass rate of 76.6% based on 659 tests โ€” well above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 46,727 miles on the odometer. With a 23.4% failure rate, the 1968 420 is rated as "Excellent" for MOT reliability.

If you own or are considering buying a 1968 Jaguar 420, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to suspension: Look for uneven tyre wear, listen for clunking over bumps, and check if the car pulls to one side. A bouncy ride suggests worn shock absorbers. Visually inspect coil springs for cracks. With relatively low average mileage of 46,727 miles, many of these vehicles are still in good mechanical condition.

Suspension โ€” 0.8% of failures

Suspension issues account for 0.8% of MOT failures on 1968 Jaguar 420 models. Suspension failures typically involve worn bushes, leaking shock absorbers, broken coil springs, and damaged suspension arms. These affect ride quality, tyre wear, and road holding. Typical repair costs: ยฃ200โ€“500. Pre-MOT check: Look for uneven tyre wear, listen for clunking over bumps, and check if the car pulls to one side. A bouncy ride suggests worn shock absorbers. Visually inspect coil springs for cracks.

Steering โ€” 0.6% of failures

Steering issues account for 0.6% of MOT failures on 1968 Jaguar 420 models. Steering failures include excessive play in the steering wheel, leaking power steering fluid, worn track rod ends, and damaged steering rack. These affect vehicle control and are closely related to suspension wear. Typical repair costs: ยฃ150โ€“600. Pre-MOT check: Check for excessive steering wheel play (more than a few inches of free movement). Listen for whining from the power steering pump. Look for fluid leaks under the car near the front wheels.

Tyres โ€” 0.3% of failures

Tyres issues account for 0.3% of MOT failures on 1968 Jaguar 420 models. Tyre failures include tread depth below the legal minimum of 1.6mm, cuts, bulges, exposed cords, and incorrect tyre pressure. Tyres are one of the most common and easiest-to-prevent MOT failures. Typical repair costs: ยฃ50โ€“200 per tyre. Pre-MOT check: Check tread depth with a 20p coin โ€” if the outer band is visible, the tyre is too worn. Look for bulges, cuts, or embedded objects. Ensure all tyres match the recommended size and load rating.
