Many motorists like to add car parts to their vehicles to improve their looks, enhance their performance or simply to give them a sense of personalisation.
But while some items, such as replacement car engines or a new gearbox, can make a big improvement to your motor, other, more frivolous additions could be doing you more harm than good.
Insurer Diamond has warned that many drivers are obscuring their view by crowding their vehicles with needless accessories.
A poll by the company found that 57 per cent of UK motorists have accessorised their car, with floor mats (35 per cent), novelty air fresheners (15 per cent) and comedy window stickers (14 per cent) being the most popular items.
However, 70 per cent of those with stickers on their rear window admitted that they obscure their view to some extent, while other items such as fluffy dice or air fresheners could cause similar problems.
Sian Lewis, managing director at Diamond, said that, considering how much time the average person spends in their car, it is perhaps unsurprising that so many want to give their vehicles a personal touch.
"But car accessories should never impede the driver's vision in any way," she added.
"If you are going to adorn your rear window with stickers or soft toys, make sure they don't obscure your view."
The most popular reason for accessorising cars is to make them more comfortable, the survey found, as identified by 29 per cent of respondents.
This was followed by motorists' desire to express their personality (13 per cent) and wanting to stand out from the crowd (11 per cent).
Perhaps unsurprisingly, 18-24-year-olds are the most likely to have personalised their car, with two-thirds (66 per cent) having done so, while just 52 per cent of those aged 35 to 54 have accessorised their vehicles.
