MEN who modify their cars spend an average of £7,000 a year on their vehicles - but only £500 on their girlfriends, says a survey.
Birmingham pips Essex as the top area for customising cars, followed by Newcastle upon Tyne, the survey by MTV UK found.
The archetypal car modifier is in his late teens or early 20s and most still live at home.
The survey revealed the five `naffest' cars according to the 1,000 car modifiers questioned.
These are the cars that customisers would not dream of driving: Smart Car, Vauxhall Corsa, Nissan Micra, Lada Samara and Skoda Felicia.
The top five naffest car accessories are seen as massage bead seat-covers, nodding dogs, stickers for radio stations, stick-on compasses for the windscreen and tea-making facilities that plug into cigarette lighters.
Jamie Shaw, creative director at Carisma automotive design in Essex, who appears in MTV's Pimp My Ride programme, said: "It's a sad day for Essex.
"The car pimping phenomenon is massive and you'll find it in all major cities. But I am surprised to see Birmingham beat Essex."
