| Car clocking|  |  | It's car tainting by numbers - car clocking investigated | 
 Inside Out exposes an illegal car clocking scam that costs motorists 
thousands and could put lives in danger.
 We discovered a Plymouth electrician 
using his skills to help unscrupulous car sellers raise the value of their used 
motors.
 
 The intriguing slogan, "You know what we do!" in a trade 
magazine caught our eye.
 We had a good idea but called Mark Freeman of DASH 
Services to make sure.
 We told him we wanted to sell a car and someone 
had suggested we phone him, though we didn聮t know why.
 
 He was quick 
to offer us "mileage correction" 聳 fixing any "problems" 
we had with our odometer.
 Miles slashed by half
 Our 
Audi A4 had no problems at all, apart from the 116,000 miles on the clock.

 Almost 
ready for the scrapyard, it was unlikely to sell for more than 拢400 聳 
until Mr Freeman stepped in.
 We met at a Plymouth garage and Mr Freeman 
asked what mileage we wanted the digital odometer to display.
 
 After removing 
the dashboard, he used a small handheld computer to quickly wipe almost 80,000 
miles off the clock before pocketing 拢150 for a job well done.
 
 Our 
Audi was now worth a tidy 拢1,500.
 
 Analogue odometers are even easier 
to alter.
 
 Clockers can just use a standard drill to turn back the numbers 
on the counter.
 Widespread scam
 There 
are dozens of crooks offering clocking services around the country, with the service 
typically described as "mileage correction".
 
 They can get away 
with offering such a service because when an odometer has broken and is fitted 
with a second-hand replacement, the devices can be legally altered.
 
 But 
it is extremely rare for this to happen.
 Usually the second-hand odometer 
keeps its original mileage and the car log book is stamped so buyers are aware 
it is not the one that came with the car, and can check any discrepancy.
 Illegal 
clocking, however, is commonplace, affecting an estimated one in 10 used cars 
and costing buyers an estimated 拢100 million a year.

 RAC 
man John Gregory says much more than their hard-earned cash is at stake.
 He 
says, "It聮s worn components and safety items which could affect somebody聮s 
life.
 "Ultimately, nobody should pay for their life. If I had my way, 
I would just lock them up and throw away the key."
 When we confronted 
Mr Freeman, he reversed his car towards our crew, grabbed presenter Sam Smith, 
tried to stop us filming and refused to answer our questions, before disappearing 
into his business premises.
 
 If you are buying a used car and are unsure 
about the mileage, here are the signs which indicate a well-travelled vehicle:
 * 
A shiny steering wheel/gear lever.* Worn pedal rubbers/driver聮s seat/carpet.
 * 
Lots of chips on the bonnet.
 You can also get the car examined 
by a vehicle history-checking company.  With some basic information about 
the car they can tell you whether it has been clocked, stolen, written-off, or 
has outstanding finance. Links relating to this story:The 成人快手 is not responsible
