Crash Test Era:
Prior to modern standardized crash testing protocols. Focused on passive safety features of the era.
Brakes:
Front disc brakes standard across the range, rear drum brakes. Some later models may have offered optional rear discs.
Steering:
Responsive rack-and-pinion steering.
Body Structure:
Reinforced A-pillars and windshield frame for rollover protection, crumple zones incorporated into chassis design.
Seatbelts:
Standard seatbelts, typically lap and shoulder belts.
Oil Change:
Every 3,000-5,000 miles (5,000-8,000 km) or 6-12 months, depending on usage and oil type.
Filter Replacement:
At each oil change (oil filter, air filter as needed).
Spark Plugs:
Inspect every 15,000 miles (24,000 km), replace as needed. Check manual for specific types and gap.
Timing Belt Chain:
These engines typically use a timing chain, requiring inspection for stretch and tension, but generally not a periodic replacement interval like a belt.
Engine Oil:
API SG or higher, SAE 20W-50 or 10W-40 (check manual for ambient temperature recommendations).
Coolant:
Ethylene glycol-based antifreeze, typically a 50/50 mix with distilled water. Check manual for specific type (e.g., green conventional).
Brake Fluid:
DOT 3 or DOT 4 (check manual for specific recommendation).
Rust Prone Areas:
Wheel arches, sills, floor pans, rear spring mounting points, convertible top well.
Carburetor Tuning:
Weber carburetors can require periodic adjustment for optimal performance and idle quality. Fuel injection systems may require injector cleaning or fuel pump checks.
Ignition System:
Points and condenser ignition systems require periodic gap and timing adjustments. Distributor cap and rotor wear.
Cooling System:
Radiator, hoses, and water pump can develop leaks over time. Thermostat failure can cause overheating.
Electrical Gremlins:
Aging wiring, connectors, and grounds can lead to intermittent electrical issues. Headlight switch, ignition switch wear.
Fiat Motorsport:
Fiat has a long and successful history in motorsport, particularly with rally racing, influencing the sporting character of models like the 124 Spider.
Styling Influence:
Designed by Pininfarina, it featured classic Italian sports car proportions and styling cues.
