Thirteen consecutive years as the UK's best-selling car. That's not a marketing claim — it's a fact that holds up to scrutiny, repeated by buyers who chose the Fiesta over every alternative in every class, year after year. And then in June 2023, Ford closed the Cologne plant that made it and stopped building them entirely.
That decision changes the used market in one specific way: there will never be a new Fiesta to undercut the used ones. The depreciation curve that normally makes a three-year-old car dramatically cheaper than the new equivalent doesn't quite work the same way here. A well-kept Mk7 Fiesta from 2020 isn't competing against new stock — it's competing against other well-kept Mk7s, and good examples have held their value accordingly.
For buyers, the question is: which Fiesta, at what price, and what to watch out for. This guide answers all three.
Mk6 or Mk7?
The used Fiesta market divides neatly into two generations worth serious consideration.
The Mk6 (2008–2017) is the older car and the one you'll find at the sharpest prices. These are proven, robust vehicles — the 1.0 EcoBoost that arrived in 2012 transformed the range, and a 2014–2017 Mk6 in good condition still makes a compelling case for itself. Parts are abundant and cheap. Every garage in the country knows how to work on them. The concerns are those that come with any car approaching or exceeding ten years old: potential rust on earlier examples (particularly the sills and rear wheel arches on pre-2013 cars built before Ford's improved galvanisation), technology that now feels dated, and the need for careful history checking on anything that's covered significant mileage. Early Mk6 cars from 2008–2012 are getting old enough that condition varies enormously. A well-maintained 2015 Mk6 is a sensible budget buy. A neglected 2009 example needs thorough inspection before you commit.
The Mk7 (2017–2023) is where the recommendation lives for most buyers. Ford gave the Fiesta a thorough overhaul — improved ride quality through revised suspension, a meaningfully better interior with softer materials and tighter assembly, a larger touchscreen, revised powertrains, and the option of technology like lane keeping assist and automatic emergency braking that the Mk6 never offered. The 2017 Mk7 was the Fiesta at its most accomplished, and the good news is that the production run was long enough — six years — that there are plenty of them on the used market at reasonable prices. A 2019–2021 Mk7 with sensible mileage and a full service history is the target car for this guide.
Which engine?
This matters more in the Fiesta than in many cars, because the engine range spans the spectrum from genuinely excellent to one you should actively avoid.
The 1.0 EcoBoost three-cylinder is the engine that defined both generations of the modern Fiesta. Available in 85PS, 100PS, and 125PS outputs depending on year and trim, it's a small-capacity turbocharged unit that delivers more performance than the numbers suggest and better economy than a larger engine could manage. In the 100PS form that most Fiestas were sold with, it pulls cleanly from low revs and settles to a relaxed cruise at motorway speeds. The three-cylinder note is distinctive — slightly vocal under hard acceleration, with a small amount of vibration at idle that's more noticeable in the cabin than it is annoying — but at a steady pace it's refined enough. The fuel economy in real-world mixed driving runs to 45–52mpg for most drivers, and higher for those who work the regenerative opportunities consciously.
The headline concern on the 1.0 EcoBoost — and it's a real one that you should check, not ignore — is the coolant issue that affected some production runs of the Mk7 cars from 2017 to approximately 2019. The 1.0 EcoBoost's cooling system is designed differently to most engines; the coolant runs through the cylinder head in a way that means a sustained overheat can lead to coolant contaminating the engine oil. Ford made engineering changes through the production run to reduce the risk, and later cars are measurably less susceptible, but the concern hasn't been formally acknowledged as a recall and some early Mk7 EcoBoosts have developed this fault. What to check: open the coolant reservoir before you go to see the car and look for a clear, bright-coloured fluid (orange, blue, or green depending on the coolant used). Remove the oil cap and look for any milky or coffee-coloured residue on the underside. Either of those symptoms warrants walking away. Clear coolant and clean oil means the engine is healthy.
The 1.5 TDCi diesel is the efficient choice for higher-mileage buyers who spend significant time on motorways. Economy figures north of 55mpg on a genuine long run are achievable, and the diesel has more low-end torque than the small petrol, which makes it feel more relaxed when carrying a full load. The caveat is the same as all modern diesels: a car that has spent its life on short urban trips has a DPF that's been asked to regenerate on journeys too short for it to complete the cycle properly. Check the service history for any DPF-related work, and listen for any excessive smoke on cold start.
The 1.6 naturally aspirated petrol, found on earlier Mk6 cars, is uncomplicated but now dated — the economy is inferior to the EcoBoost and the performance less interesting. These cars use a timing belt rather than a chain, which needs replacement at the manufacturer's specified interval. If the service history doesn't confirm this, budget for it or use it as a negotiating point.
The PowerShift dual-clutch automatic is the transmission to avoid on Mk6 cars. Ford's dry dual-clutch unit was fitted to some Fiesta automatic variants and proved troublesome in real-world use — it hesitates, shudders at low speeds, and has been expensive to repair or replace when it fails. If you want an automatic Mk7 Fiesta, the later versions moved to a different setup that is considerably better behaved. Automatic Mk6 Fiestas should be approached with caution and a test drive specifically in traffic.
Which trim level?
The Fiesta trim hierarchy is long and changes across the production run, but the meaningful choices on the used market cluster around a few levels.
Zetec is the volume spec and often the best value. Climate control, Ford's SYNC infotainment, alloy wheels, and enough equipment to be comfortable without the cost of extras you might not use. The most common car on the used market, which means the most competition and often the sharpest prices.
Titanium adds heated front seats, a larger touchscreen, rear parking sensors, and upgraded interior materials. On the used market the premium over Zetec often compresses to the point where Titanium represents genuine value — particularly on Mk7 cars where the larger screen is noticeably better to use.
ST-Line adds visual sports styling — different bumpers, lower suspension, larger alloys, sports seats. The ride is firmer than Zetec or Titanium, which some buyers prefer and others find wearing on British roads. Worth choosing if the look matters to you; less so if ride comfort is the priority.
Active is the crossover-styled variant on the Mk7 — raised ride height, plastic body cladding, and a slightly more rugged appearance. In practice it drives like a standard Fiesta with a higher seat, which suits some buyers perfectly. Practically useful for light off-road use, dog-owner-friendly, and the raised ride soaks up potholes better than the ST-Line.
The Fiesta ST is a different car entirely. The 1.5 three-cylinder turbo with 200PS is a genuine performance car that routinely appears near the top of hot hatch rankings, and the used market price reflects that. If you're considering one, do the research specifically on the ST — it's outside the scope of a general Fiesta guide.
What goes wrong?
The EcoBoost coolant concern is covered above — check it before you buy. Beyond that:
Door seal deterioration on older examples. Mk6 and some early Mk7 cars develop worn or hardened door seals that allow water to track into the cabin. Wet rear footwells are the symptom — run your hand under the rear carpet during the viewing. Not expensive to fix, but worth knowing before you agree a price.
Rear beam axle noise on high-mileage Mk7s. The Fiesta uses a torsion beam rear suspension — a simple, robust design but one that can develop a clunking noise from the rear when the bushes wear. The symptom is a knock over rough surfaces or when reversing. Budget for bush replacement on anything over 80,000 miles that hasn't had this attention.
Infotainment issues on pre-2019 Mk7. The SYNC 3 system in the early Mk7 can be slow to respond and occasionally freezes. It's rarely a fault that can be fixed cheaply — if the touchscreen is unresponsive during the test drive, factor that into your assessment of the car's overall condition.
Rust on pre-2013 Mk6 sills and arches. Early Fiestas built before Ford improved the corrosion protection can show rust at the sill edges and rear wheel arch lips. Surface rust that's been ignored becomes structural rust over time. Run your fingers along the sill seams on any pre-2013 example.
What you should actually pay
- Mk6 1.0 EcoBoost Zetec (2014–2017): £6,500–£10,000
- Mk7 1.0 EcoBoost Zetec (2017–2019): £9,500–£13,500
- Mk7 1.0 EcoBoost Titanium/ST-Line (2019–2021): £12,500–£17,000
- Mk7 1.0 EcoBoost Active/Titanium X (2021–2023): £15,000–£20,000
The Fiesta's values have held better than most superminis since production ended. Don't expect to find one significantly below these ranges from a reputable seller — if the price looks too good, investigate why before you get excited about it.
Before you see it
Check the MOT history before you go. The Fiesta's long production run means there's a deep MOT record on most examples, and mileage consistency across tests is a reliable indicator of honest use. Any car where the mileage jumps significantly between consecutive tests warrants an explanation.

On the test drive: start from cold if possible and watch the temperature gauge settle — it should reach normal operating temperature and stay there. On any 2017–2019 1.0 EcoBoost, check the coolant reservoir colour and the oil cap underside as described above. Test any automatic gearbox specifically in slow-moving traffic. And spend time on a road with imperfect surfaces to check the rear suspension for any knocking.
Should you buy one?
A 2019–2022 Mk7 Fiesta in Titanium or ST-Line trim, 1.0 EcoBoost 100PS manual, full Ford service history, clean MOT: yes, without significant reservation. The Fiesta at its best is one of the most accomplished small cars Britain has produced, and the fact that it's no longer made hasn't diminished what makes a good example good. The economy is real. The driving feel is genuinely rewarding in a way that many small cars aren't. The running costs are low, parts are plentiful, and the service network covers every corner of the country.
The things that could go wrong are all checkable. The things that will go right are twenty-three years of proven track record. There's a reason it was the country's best seller for so long, and it had nothing to do with advertising.
