Market Position:
The Fiat 124 Spider (also known as the Fiat Pininfarina Spider or Pininfarina Azzurra in later years) was a classic Italian convertible sports car, renowned for its elegant design, rear-wheel-drive handling, and affordable performance. For 1990, it represented one of the last iterations of a long-running and beloved model.
Competitive Analysis:
Competed against other affordable two-seater sports cars of its era, such as the Mazda Miata (NA), Toyota MR2, and potentially entry-level versions of more premium convertibles. Its strengths were classic styling and Italian flair.
Key Features:
Classic Italian styling by Pininfarina, rear-wheel-drive chassis, convertible soft-top, capable handling characteristics, relatively simple mechanicals making it a favorite for enthusiasts and DIY mechanics.

Rear Axle Fluid Capacity:
Refer to manual for specific capacity, typically around 1.3 - 1.5 liters.
Common Issues:
Rust (especially wheel wells, rocker panels, floor pans), aging rubber components (hoses, seals, bushings), electrical gremlins (corroded connections), carburetor wear (if applicable, though 1990 is likely injected), clutch wear, potential for timing belt failure if not maintained.
Timing Belt Importance:
The Lampredi twin-cam is an interference engine. Timing belt failure will likely cause piston-to-valve contact and severe internal engine damage. The manual's 'Timing Belt Replacement Helper' is a critical resource.
Brand Heritage:
Fiat has a long history of producing innovative and stylish cars, particularly in the small and sports car segments. The 124 Spider is a direct descendant of Fiat's sporting lineage.
