1999 TVR GRIFFITH

Symptoms: Rust visible on tubular steel chassis, particularly rear suspension mounting points, Creaking or flexing over bumps, Failed MOT/inspection due to structural rust, Corrosion around outriggers and floor pan jacking points

Fix: Chassis-out restoration often required; serious repairs involve removing body (fiberglass separates from chassis), sandblasting affected tubes, welding in repair sections or replacement tubes, then reassembly. 40-60 hours labor minimum for proper repair, often much more.

Estimated cost: $8,000-15,000

Typical onset: 40,000-80,000 mi

Symptoms: Temperature spikes in traffic or spirited driving, Coolant loss with no visible leaks, Oil cooler or engine oil cooler failures, Head gasket failure from repeated overheating, Warped heads requiring engine rebuild

Fix: System undersized from factory. Typical fix involves upgraded radiator, high-flow water pump, oil cooler replacement/upgrade, thermostat, and complete coolant flush. If heads are warped, you're looking at engine-out rebuild with head resurfacing. 8-12 hours for cooling upgrades; 50-80 hours for full engine rebuild.

Estimated cost: $1,500-3,000 for cooling system; $8,000-12,000 for engine rebuild

Typical onset: 60,000-90,000 mi

Symptoms: Third gear synchro failure causing crunching on downshifts, Difficult shifting when hot, Oil leaks from transmission mounts and cooler lines, Complete transmission seizure in worst cases

Fix: T5 gearbox not really rated for the V8 torque. Rebuild involves removing transmission (tight quarters, 6-8 hours), synchro replacement, bearing refresh, new seals. Many upgrade to T5Z or Tremec TKO during rebuild. Transmission mounts wear rapidly and need replacing every 30k miles (2 hours).

Estimated cost: $2,500-4,500 for rebuild; $300-500 for mounts

Symptoms: Intermittent or complete headlight failures, Gauges reading erratically or not at all, Starting issues despite good battery, Alternator overcharging or undercharging, Corroded grounds causing random electrical gremlins

Fix: Hand-built wiring means every car is unique. Common issues: headlight assemblies corrode and fail (3 hours per side to replace), main ground points need cleaning and dielectric grease, alternator typically needs rebuild or replacement by 70k miles. Diagnosis is time-consuming due to poor wiring documentation. Plan 2-6 hours for electrical troubleshooting per issue.

Estimated cost: $500-2,000 depending on scope

Typical onset: 50,000-80,000 mi

Symptoms: Uneven braking or pulling to one side, Brake pedal going to floor, Calipers sticking causing dragging and overheating, Brake fluid contamination from old rubber seals

Fix: AP Racing or Girling calipers require full rebuild with new seals, pistons, and hardware. All four calipers should be done simultaneously. Master cylinder typically fails around same time. Front calipers 4 hours, rears 3 hours, master cylinder 2 hours. Parts availability can be challenging.

Estimated cost: $1,800-3,000 for complete brake system overhaul

Typical onset: varies with storage conditions

Symptoms: Rough running or hesitation under load, Hard starting when hot, Fuel smell in cabin, Poor fuel economy

Fix: Steel fuel lines rust from inside out, especially if car sits. Fuel filter clogs from tank sediment (should be changed every 2 years, 1 hour job). Fuel pump failures common. In severe cases, tank removal and cleaning or replacement required (8-10 hours labor for tank work).

Estimated cost: $200-400 for filter/pump; $1,500-2,500 for tank replacement

Symptoms: Creaking and squeaking from body panels, Visible separation between fiberglass body and steel chassis, Door alignment issues that worsen over time, Stress cracks in gelcoat around mounting points

Fix: Fiberglass body is bonded to chassis with adhesive that degrades over time and with oil leaks. Proper repair requires body-off, cleaning both surfaces, re-bonding with proper adhesive (Sikaflex or equivalent). 30-40 hours labor for body removal, prep, and reinstallation.

Estimated cost: $4,000-7,000
