London ( CNN ) -- When he was a 15-year-old schoolboy , Paul Wallace joined his father to see an exhibition of the world 's most ostentatious automobiles . Wallace was entranced , and pulled out his camera to take photos . The visit , taking in Aston Martins , Ferraris and Lamborghinis , would prove the beginnings of his lucrative YouTube video channel . `` I sort of fell on my feet in that sense , '' the entrepreneur told CNN . Wallace , still too young to get a driver 's license , began filming supercars around London , and uploading them to YouTube . The street shots and low resolution videos brought the cars `` to life '' for fans unable to afford one , Wallace said . Now , the 23-year-old university graduate earns up to Â£4,000 ( $ 6,722 ) a month from the advertisements displayed on his YouTube video channel , Supercars of London . His account has had almost 70 million views , with hits coming from all over the world . Wallace is now making a living from the site -- one of a number of YouTubers building a business out of the video platform . Wallace has used his earnings to indulge his passion : buying his own supercar . The purchase of a Â£55,000 Audi R8 enabled Wallace to return his mom 's Ford Focus , which had been on loan . `` I 'm very much at the early stages of where I want to be , say , in five to 10 years time , '' Wallace told CNN . And his supercar ambition remains unchanged . `` A Lamborghini is what I aspire to , '' Wallace said , standing next to one in the supercar servicing garage in Watford , where he works .
Paul Wallace became entranced by supercars when he visited an exhibition , aged 15 . Now , the 23-year-old has made a YouTube business out of filming them in London . The videos are shot on his iPhone and show him driving around with one eye open while listening to music - or at least trying to.
