Avoid these popular used cars due to poor 'build quality and common faults'

While many car enthusiasts argue that there's no such thing as a bad motor these days, there are still numerous models that second-hand car buyers would do well to avoid.

MG6

This model, which played a key role in reviving the MG brand, was designed in China but built in the UK. It received high praise for its generous standard features and competitive pricing against rivals like the Skoda Octavia and Ford Mondeo.

However, the interior design and build quality were deemed subpar compared to competitors, while the limited engine options were seen as unrefined, and in the case of the V8, notably fuel-hungry.

Vauxhall Mokka

Although the Mokka's tried-and-true mechanics are fairly reliable, the SUV is considered rather dull to drive, particularly due to its rigid ride quality.

Moreover, some of the earlier models are known to have faulty adaptive headlights and rattles from the front windows and clutch pedal relay, reports the Express.

Ford Fiesta 1.0 EcoBoost

Originally designed to be an incredibly efficient little powertrain, early versions of the EcoBoost engine had a wet belt—a timing belt lubricated by engine oil.

While Ford asserts that the belt can last 10 years or 150,000 miles before replacement, constant exposure to oil has caused some timing belts to deteriorate. This can clog up the oil filter and lead to very expensive repairs.

Ford Ka

First-generation Ford Kas are now incredibly affordable, but they're notorious for rust issues. Prospective buyers should inspect the sills, rear edges of the door shuts, and around the fuel filler cap.

Early models of the Ka were equipped with a 1.3 Endura-E petrol engine, a relic from the Ford Anglia of 1959. While later models boasted more efficient Duratec and Zetec engines, early Kas are known to be somewhat slow and fuel-guzzling compared to their competitors.

Land Rover Discovery 4

Sharing the same platform as the Range Rover Sport, used Discovery 4s can be snapped up for as little as £4,000, making them an attractive option. However, like some other previous models in the JLR range, they're prone to electrical problems.

A study by online retail platform Carwow revealed that the average Discovery owner spent around £2,041 on repairs, with some facing repair bills as high as £25,695 to rectify certain faults.
