The Ford Sierra, with its distinctive 'jelly mould' styling, carved a niche for itself in New Zealand. From family transport to boy racer project, it offered practicality and potential in equal measure. Imported models added unique flavour to the mix. Understanding its quirks and common issues is key to keeping these classics on the road.
Rust is the primary enemy, particularly around wheel arches, sills, and strut towers. Expect to address rear wheel bearing failure from time to time. CV joints can wear, especially on high-mileage cars. Electrical gremlins and dashboard cracking due to sun exposure are also common.
When it comes to WOF time, pay close attention to rust (especially around wheel arches, sills and strut towers). Suspension bushes and ball joints are prone to wear. Be sure to check for engine oil leaks (often from the rocker cover or rear main seal), cooling system leaks (radiator and hoses), and brake condition (corrosion, leaks).
The Sierra was a bit of a design statement when it first appeared. Aerodynamic efficiency was prioritised, leading to a shape that divided opinions, yet it gave the Sierra a surprisingly spacious interior. Though simple mechanically which made it fairly easy to own and repair, the New Zealand sun and roads can take their toll.
Why It Matters (Motorsport Heritage): While purpose-built RS500 Cosworth Sierras were rare on NZ racetracks, their global touring car success resonates with local enthusiasts. The Sierra's rear-wheel-drive layout and readily available performance parts made it a popular choice for club-level motorsport, especially drifting circuits around the country.
