Aston Barclay Insights report has revealed that average prices of diesel and petrol vehicles in the used car market rose to a record high in Q4 2018.

It said that the market “continued to thrive” in the wake of last September’s introduction of the Worldwide Harmonised Light Vehicle Test Procedure (WLTP).

According to the remarketing specilaist, the new emissions test legisltaion, introduced in September 2018, has helped drive activity within the used vehicle sector culminating in average prices for diesel and petrol vehicles reaching a high of £8,818 and £4,651 respectively during Q4, a rise of £67 and £326 respectively over Q3.

Aston Barclay’s group managing director, Martin Potter, said: “Q4 saw the impact of September’s WLTP introduction continue to rumble on within the used vehicle sector, with restricted supply and increased demand resulting in price increases across all sectors except for late and low cars.”

WLTP caused contract extensions within the leasing sector which restricted the supply of ex-fleet cars coming back into the used market. Fleet prices increased from £9,960 in Q3 to £10,009 in Q4 and rose by 6.5% (£613) from Q4 2017.

Overall, average used prices across all stock categories rose year-on-year at Aston Barclay.

Prices in the dealer part exchange (young 55-78 months, old 76-126 months and budget 126 months+) sectors all rose in Q4 to record 2018 levels as used car retailers refocussed their business strategies on an older age and profile of stock to cater for demand.

“The price increases with the dealer part exchange sector during Q4 have been healthy and with Brexit looming the demand for cheaper used cars looks set to continue,” said Potter.

“The coming 12 months look positive for the used vehicle market yet will undoubtedly bring challenges too – the obvious one being how Brexit ultimately plays out.”

Part exchange prices of the respective three dealer part exchanges rose by 7.6% (£450), 13.7% (£412) and 15.1% (£159) to £6,371, £3,416 and £1,209 respectively in Q4.

These price increases show dealer vendors that part exchanges upwards of six years of age provide a sound profit opportunity.

Prices softened slightly during Q4 in the late and low sector to £15,248 (Q3 £15,589) after a hectic Q3 when demand and prices rose significantly in anticipation of WLTP’s introduction.

Prices of hybrids and EVs also slowed down in Q4 to £12,714 from £13,073 in Q3, mainly due to a restricted mix of stock, however, volumes were up 38.6% in 2018 from 2017.

“The used vehicle market is in a strong, resilient position and held firm during its market challenges in 2018,”said Potter.
