Motorists looking to sell their used car have been warned that interior issues can significantly reduce its resale value, with visible stains and carpet damage topping the list of deal-breakers. According to research by Vertu Motors, 40 per cent of automotive technicians surveyed cited stained or damaged upholstery as their primary concern when assessing a vehicle's appeal to potential buyers.
Persistent unpleasant odours, such as those from smoke, pets or dampness, were flagged by 30 per cent of experts as a major turn-off, while a further 25 per cent pointed to malfunctioning internal controls. The findings highlight how easily overlooked details can make the difference between securing a good price or settling for a lower offer in a competitive market where over four million used cars have been sold in the UK so far in 2025.
Vertu Motors advises sellers to tackle visible stains and wear on seats and carpets through deep cleaning, using methods such as a baking soda and water paste on fabric stains. To eliminate odours, they recommend removing the source, using baking soda or charcoal to absorb smells, and replacing the cabin filter. Ensuring all interior controls are fully functional is also crucial, as even minor electrical faults can raise major concerns for buyers.
Presenting a fresh, clean and working cabin not only reassures buyers but helps sellers secure the best possible resale price, the experts stress. A shabby interior creates an immediate negative impression that is hard to overcome, suggesting a lack of general care.
