Top 5 Most Reliable Used Vans for Small Businesses

Reliability is not just about avoiding vehicle breakdowns. It is about parts availability, affordable servicing, the strength of the dealer network, and how well a van holds up under the kind of sustained daily use that commercial vehicles face. Some vans are brilliant when new, but costly to keep on the road. 

At Exeter Diesels, we have sold thousands of used light commercial vehicles to businesses across Devon and the South West. These five vans come up again and again as the ones our customers return for, the ones that are still going strong years after purchase, and the ones that consistently justify their reputation.

1. Ford Transit Custom

Best for: Medium-sized loads, trades, deliveries, and general business use.

The Ford Transit Custom is, by some distance, the most popular van in the UK and for good reason. It hits every practical mark: excellent load space, comfortable cab, strong diesel engines (the 2.0-litre EcoBlue unit is particularly well-regarded), and a dealer and parts network that covers virtually every corner of the country.

For small businesses, the Custom’s widespread availability in the used market means more choice at every price point. Finding a well-maintained example with a documented service history is straightforward. Independent garages are familiar with the platform, keeping servicing costs competitive.

What to look for on used examples: The 2.0 EcoBlue engine replaced the older 2.2 TDCi unit around 2016–2017 and is a significant improvement. Look for Euro 6 examples where possible for clean air zone compliance. DPF issues can affect short-journey vehicles; check for regeneration warning history. The six-speed manual gearbox is robust; automatic versions are available and increasingly desirable.

Typical used price range: £10,000–£20,000 depending on age, mileage, and specification.

2. Volkswagen Transporter T6/T6.1

Best for: Businesses where presentation matters, passenger-cargo hybrid use, and premium trades.

The Volkswagen Transporter has an almost cult-like following in the UK trades community, and the T6 generation (2015 onwards) represents one of the best all-round used van purchases available. It is more expensive than the Transit Custom, but it holds its value exceptionally well, feels genuinely car-like to drive, and has a reputation for going well past 200,000 miles with proper maintenance.

The 2.0-litre TDI engine family is a proven, durable unit. The DSG automatic gearbox option is excellent and popular. Build quality is a step above most rivals, which matters when a van is representing your business.

What to look for on used examples: DSG gearboxes need their oil changed every 40,000 miles; check that this has been done. Early T6 models had some DSG software issues that have since been resolved via updates. Check for signs of conversion work if the van has been used as a camper or shuttle, these alter the load-carrying dynamics and can mask wear.

Typical used price range: £14,000–£28,000, depending on specification and age.

3. Mercedes-Benz Sprinter

Best for: High-volume work, courier fleets, businesses needing maximum payload

The Mercedes-Benz Sprinter is the definitive large panel van. It offers maximum load volume and payload capacity, a commanding driving position, and diesel engines, particularly the OM651 and the newer OM654, built for high-mileage commercial use. For businesses that move large amounts of goods or need a specialist conversion base (refrigerated van, welfare unit, Luton box), the Sprinter is the benchmark.

It is not the cheapest van to buy or to service, and parts costs are higher than those of Ford or Vauxhall. However, its sheer capability and the depth of the market mean it remains an excellent value for businesses with the right workload.

What to look for on used examples: The OM651 engine had well-documented issues with swirl flaps and EGR systems on earlier versions; check for signs of repair or updated parts. The newer OM654 unit is considerably more reliable. Rear-wheel drive versions handle better when loaded; front-wheel drive models are more economical on lighter loads.

Typical used price range: £12,000–£25,000 for suitable business examples.

4. Ford Transit Connect

Best for: Small load requirements, urban businesses, sole traders needing an economical van

The Ford Transit Connect is the compact sibling of the Transit Custom and fills a very specific gap in the market brilliantly. It is smaller, easier to park in tight urban spaces, more fuel-efficient, and cheaper to insure and tax while still offering a practical load area for tools, equipment, or moderate delivery volumes.

The 1.5-litre EcoBlue diesel engine in post-2018 Connect models is efficient and durable. Ford’s extensive service network keeps running costs manageable, and the van’s widespread popularity means used examples in good condition are never hard to find.

What to look for on used examples: Earlier models (pre-2018) used a 1.6 TDCi engine that had some reliability issues with DPF and turbo on high-mileage examples. The post-2018 facelift with the 1.5 EcoBlue is the version to aim for. Check the payload rating if you regularly carry heavy tools. The Connect is not a heavy-lifter.

Typical used price range: £8,000–£16,000.

5. Vauxhall Vivaro / Renault Trafic

Best for: Trades needing a mid-size van with good value for money.

The Vauxhall Vivaro and Renault Trafic are mechanically near-identical vans built on a shared platform, up to the third-generation Vauxhall variant. They offer Transit Custom-rivalling load space, comfortable cabs and in recent generations, the current third-generation Vivaro (2019 onwards) is an impressive step forward in quality and refinement.

The 1.5 and 2.0-litre BlueHDi diesel engines (shared with PSA/Stellantis) are efficient and reasonably reliable. Used Vivaro examples are often priced more competitively than equivalent Transit Customs, making them a strong value proposition for budget-conscious buyers.

What to look for on used examples: Earlier second-generation Vivaro (2014–2019) used a 1.6-litre twin-turbo diesel that had some reliability concerns, particularly around turbo and gearbox durability. The third-generation 2019-on model is a significant improvement. Check for full service history and DPF condition, particularly on vans that have done a lot of short-journey urban work.

Typical used price range: £9,000–£18,000.
