Car owners that have kept their vehicle for over 10 years are coming back to the new car market due to strong PCP deals, according to Glass’s.

Rupert Pontin, head of valuations at Glass’s, said there has been a 50% increase on the number of cars over 10.5 years old being sold at auction in the UK.

He said: “We believe this is because large numbers of buyers are selling their bangers and signing up to low-cost new and used car PCP deals to get behind the wheel of a newer model.

“However, instead of this flood of bangers entering the market leading to a collapse in values, they have actually increased quite substantially.”

The average auction price for a 10.5 year-plus car in January 2013 was £725 but in June of this year, it was £875, according to figures obtained by Glass's.

Pontin said enough new buyers are entering the market to soak up the extra volume and the market for older vehicles is actually in “excellent health”.

He said: “Partially this is as a result of improving economic conditions – more people are feeling confident about buying and running a car at the entry level – but also the quality of older cars on sale is improving all the time.

“We see many bangers going through auction in excellent condition at very reasonable prices and, for many people, they make extremely sensible purchases.

“It is very much a case of ‘The banger is dead. Long live the banger.”

Pontin said that the question for the medium term was how many more people would opt for a PCP deal on a newer car and whether banger values would continue to increase over time.

He said: “The number of people switching into PCPs does not really show any sign of slowing down and this means that the volume of older vehicles on the market will continue to grow. At some point, this will lead to oversupply and falling values but it is quite difficult to predict exactly when.”
