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 1997 TVR Cerbera

  • ✓Engine health is paramount; demand proof of engine rebuilds or upgrades from a recognized TVR specialist (e.g., Str8Six, TVR Power).
  • ✓Check the tubular chassis outriggers for severe rust, just as with the Griffith/Chimaera.
  • ✓Test the clutch weight and bite point; the clutch mechanism is very heavy and the slave cylinder seals frequently fail.
  • ✓Inspect the unique electronic door opening buttons (under the mirrors) to ensure they work and haven't succumbed to water ingress.
  • ✓Listen for a rattling timing chain on the Speed Six engine, indicating impending failure.
  • ✓Ensure the complex "AJP" V8 (if fitted) has been serviced strictly according to schedule, prioritizing high-quality synthetic oil.
