Used cars spares is highly unregulated i suppose impossible for the environment agency to control although i doubt they would not take issue with somebody dismantling a car for a few personal spares and it would be a sad day if they did.
The permits involved is complicated,waste control is very stringent ,hazardous waste as to be disposed of by waste carriers with waste transfer documents etc.and insurers do charge heavy premiums for car dismantlers.
Also vehicles are supposed to be issued with certificate of destruction,i used to have a breakers yard to do it correctly is very costly and the insurance underwriters have several clauses that must be adhered to.
More and more MGF MGTF are being purchased for low sums, some i get offered which i turn down and see on the internet with parts at high prices weeks after, my website specifically states i do not break roadworthy cars as i get fed up of the phone calls from sellers.
I only previously purchased insurance write offs and concentrate on sourcing new parts and have provided some of the cheapest prices in europe for new parts.
MGF MGTF is a personal addiction of mine i often inject my own personal capital funds into the the business, as a whole it runs at a loss as i enjoy sourcing parts and have bought heavily in the last two years, Some SAIC parts which shipping and import duty is also costly along with the pound against us dollar at the moment is not good for any importer in the UK.
My favourite finds are Genuine MG ROVER legacy parts although most manufacturers who supplied Longbridge direct pre 2005 simply are not interested, the large businesses do not find it viable to make 100 of a certain part and old stock unused is treated as surplus but must be bought as a job lot which can run into tens of thousands.
So yes when somebody buys a few MGF MGTFS for peanuts and commands OTT prices and makes up a ebay name mgf best in the world etc i too find it a bit jumping on the bandwagon but where money is to be made somebody will muscle in and as they say its a free country.
Running any business can be costly, some of the highest turnover companies in the world have failed. Expenses add up,unit premises,insurance,postage employees.ebay & paypal fees,vat,accountants,hmrc tax,advertising etc the profit margin of a item for a business attempting to run legitimately is often the small picture but rightly so for the many unregulated traders who claim to have a interest in MGF MGTFS it gets right up my nose too.
