What changed for 1996

  • •Launch of TVR's first 2+2 fixed-head coupé featuring in-house designed engines and lightweight composite bodywork
  • •Bespoke 4.2-litre AJP8 flat-plane crank V8 produces 360bhp, mated to a BorgWarner T5 five-speed manual gearbox
  • •4.5-litre AJP8 V8 introduced in 1997 producing 420bhp with upgraded AP Racing front brake calipers
  • •4.0-litre Speed Six straight-six engine option introduced in 1999 offering 350bhp and 330lb ft of torque
  • •Aircraft-style cockpit with steering wheel auxiliary pod, floor-mounted starter switch, and hidden electric door releases

Common MOT watch-outs

  • !Severe corrosion of the tubular steel chassis outriggers and rear suspension backbone mounts hidden by bodywork
  • !Excessive play in front wishbone ball joints and perished anti-roll bar drop link bushes from hard road use
  • !Exhaust emissions test failure on AJP8 engines due to drifted throttle pot synchronisation or tired lambda sensors

All Known Issues

AJP8 Engine Tappet Adjustment

SeriousEngine

The Speed Eight engine requires regular, specialist tappet adjustments. If ignored, it can lead to valve damage.

Est. Repair Cost: £600–£1,000 (Service item)
Warning Signs:

Loud mechanical clatter, Loss of power

What to Inspect:
  • Check service records for "Valve Clearance" checks.

Chassis Rot (Main Rails & Outriggers)

SeriousSuspension & Chassis

Like the Chimaera, the Cerbera chassis is prone to rust, but access is even more restricted, making inspection difficult.

Est. Repair Cost: £3,000–£6,000
Warning Signs:

Visible rust, Cracked powder coating

What to Inspect:
  • Inspect the area around the rear suspension mounts and front outriggers.

Cooling System Overheating

SeriousCooling System

The cooling system is a known weak point. Faulty fan switching relays, inefficient radiator airflow and coolant leaks can cause overheating in traffic. Water pump and radiator seal failures are common even on well-maintained cars.

Est. Repair Cost: £400–£1,200
Warning Signs:

Temperature gauge climbing in traffic, Coolant loss, Steam from engine bay

What to Inspect:
  • Check coolant level and condition.
  • Test fan switching at idle.
  • Inspect radiator for leaks and corrosion.
  • Many owners upgrade to aluminium radiators.

Electrical Gremlins & Wiring Loom

ModerateElectrics & Electronics

Hand-built wiring harnesses vary car to car, leading to inconsistent electrical reliability. Central locking, door solenoids, immobilisers, lights and cooling fans are all prone to moisture-related failures.

Est. Repair Cost: £100–£500 per fault
Warning Signs:

Central locking failure, Intermittent light operation, Cooling fan not triggering, Immobiliser preventing start

What to Inspect:
  • Test all electrical functions including lights, wipers, fans, and door buttons.
  • Check for corroded earth points and loose connectors.
  • Ask about any electrical rebuilds or upgrades.

Buying Tips for 1996 TVR Cerbera

  • Inspect the tubular steel chassis outriggers on a ramp; terminal rot requires an expensive body-off restoration
  • Verify specialist service history for 24,000-mile AJP8 valve clearance shimming or 12,000-mile Speed Six checks
  • Test all electrical functions including under-mirror door poppers, auxiliary instrument pods, and cooling fan relays
  • Listen for clutch thrust bearing squeal or heavy pedal action indicating fractured pressure plate diaphragm fingers
