Parts availability and escalating costs

ModerateBodywork & Rust

With production ceased and the Mazda-Fiat partnership ended, 124 Spider-specific parts are becoming scarce and expensive. Body panels (especially aluminium items), windscreens, key fobs and even the bonnet pedestrian-safety actuators can be on backorder for months. Some cars have been written off due to parts being unavailable for minor accident repairs.

Est. Repair Cost: £200–£10,000+
Warning Signs:

Long wait times for replacement parts, Dealer unable to source 124-specific components, Very high quotes for bodywork repairs, Key fob replacement discontinued in some markets

What to Inspect:
  • Ask the dealer to check part availability before buying
  • Check for any previous accident repair history
  • Verify key fob condition and whether a spare exists

MultiAir oil drain-back when sitting unused

ModerateEngine

If the 1.4 MultiAir engine sits unused for several months, oil can drain from the hydraulic MultiAir unit ("the brick"), affecting the valve train and preventing the engine from starting due to lack of compression. The fix is usually to crank it until the unit re-primes, but repeated occurrences can damage the unit.

Est. Repair Cost: £0–£500
Warning Signs:

Engine cranks but will not start after extended storage, Rough idle on first start-up, Misfire immediately after sitting unused

What to Inspect:
  • Ask whether the car has been stored or sat unused for long periods
  • Start it from cold and listen for a smooth idle
  • Check for any MultiAir unit replacement invoices
