Abarth 124 Spider

The Abarth 124 Spider took the excellent rear-wheel-drive chassis of the Mazda MX-5 ND and injected it with a turbocharged Italian heart and aggressive styling. Launched to critical acclaim, it positioned itself as a more visceral, torquey alternative to its Japanese sibling, complete with a raucous Record Monza exhaust. In the UK, it has become a sought-after modern classic, prized by enthusiasts who appreciate the blend of reliable Mazda electronics and charismatic Fiat Chrysler powertrains. Overall reliability is excellent, largely thanks to the underlying Mazda architecture, though the Abarth-specific engine components require specialist knowledge. It is perfect for weekend drivers wanting traditional sports car thrills with modern dependability.

Abarth 500 / 595 / 695 (Type 312)

The Abarth 500, later rebranded as the 595 and 695, is a high-performance derivative of the beloved Fiat 500 city car. It established a cult following in the UK by offering riotous exhaust notes, characterful Italian styling, and genuinely entertaining performance in a compact, accessible package. In the UK market, it occupies a unique niche, appealing to younger enthusiasts and city dwellers who want a charismatic hot hatch without the physical footprint of a Fiesta ST. Reliability is generally sturdy regarding the 1.4 T-Jet engine, but the car is known for niggly electrical issues and interior squeaks. It best suits buyers willing to sacrifice ride comfort and practicality for a heavy dose of driving theatre.

About Abarth Reliability

Abarth transforms standard Fiats into high-performance "Scorpions." While they share basic platforms with Fiat, their higher-tuned engines and firmer suspension bring unique maintenance requirements. Enthusiast ownership usually means better service history, but they are often driven harder. The brand was revived by Fiat in 2007 and has become a firmly established part of the UK hot hatch landscape. In the UK, Abarth benefits from the extensive Stellantis (formerly FCA) dealer network, with parts readily available and servicing costs reasonable for a performance car. The 1.4 T-Jet engine is generally robust when maintained correctly, and a large aftermarket tuning community exists. The MTA (robotised manual) gearbox is the model to avoid—expensive to repair and less engaging than the manual. UK-specific considerations include insurance groups that are moderate for the performance (typically groups 20–30), and the Record Monza exhaust valve that is notorious for seizing in UK conditions due to road salt and heat cycles. The cars are popular with younger drivers, which can mean examples have been driven hard or modified. The 500-based models are compact enough for UK town driving but can feel firm on poorly maintained B-roads. Depreciation is moderate—the Abarth 595/695 holds its value reasonably well, particularly the Competizione and Essesse variants. The 124 Spider has depreciated more steeply, partly due to its MultiAir engine's reputation for oil-related issues. Abarths are best suited to enthusiasts who want an engaging, characterful hot hatch and are willing to maintain them properly. They are less suited to those seeking a refined daily commuter or who are put off by the occasionally "Italian" approach to build quality.

Common Abarth trouble spots

  • Record Monza exhaust valves frequently seize due to road salt and heat, requiring regular lubrication or replacement.
  • Rear axle bushes perish prematurely, causing clonking and MOT failures, just like the standard Fiat 500.
  • Door handle hinges are prone to snapping, a frustrating but common Italian car quirk.
  • The MTA (Competizione) semi-automatic gearbox can be jerky and expensive to repair if the actuator fails.
  • Heater blend door actuator failure is common, requiring dashboard removal to access and replace.
  • Turbocharger wear on higher-mileage T-Jet models—listen for whistling or metallic noises under acceleration.

What to check on used Abarths

  • Check for a meticulous service history; T-Jet engines are robust but need high-quality oil changes every 6,000–9,000 miles.
  • Listen for "tinkling" or "whistling" from the turbo, which could indicate a failing IHI or Garrett unit.
  • Inspect the Record Monza exhaust valve (if fitted); they are notorious for seizing in the open or closed position due to road salt.
  • Look for signs of track use, such as unusually worn tyre shoulders or heat-discoloured brake calipers.
  • Prioritise manual gearboxes over the MTA robotised manual for better reliability and a more engaging driving experience.
  • Check the rear axle bushes—they perish prematurely and are a common MOT failure point.
  • Test the heater blend door actuator; failure is common and requires a dashboard-out job to fix.
  • On 124 Spider models, verify the MultiActuator has been serviced with correct Selenia oil—the unit is very sensitive to oil quality.
