Yeah and their Admin fee's make £150 look like a drop in the ocean.
So if you aren't sure about what "Admin" a dealer does to get your car on the road.
Paperwork for the sale includes legal documentation that the Govt and monitoring authorities require, plus whatever the Dealer has to do for the DVLA, AFRL and even for whatever system they use such as Kalmazoo etc. Then there is dealer required Documentation for Accounts and internal checks. Then there is Admin in prep'ing the car to ensure everything is done for you to collect. I won't go into how many check sheets need to be done. 1 for Admin, 1 for Salesman, one for Sales Manager to oversee the other 2 etc.
Then there is Finance Paperwork, if you don't want Finance there is paperwork to say you don't want finance and that it has been offered to you as a requirement. Then there is Insurance Documentation and additional options such as paint treatments and GAP insurances. Again if you don't want these the Salesman has to get you to sign to say it was offered, not for legal reasons but because his boss will sack him if he doesn't "sell" which is his job!
Then there is admin for the handover, final check lists, Inspection by the Saleman to make sure its perfect (he has to sign to say he's done it so it's on his head if you find an issue). Finally on collection the Saleman has to do another check on your used car, ensure its the same as when he last inspected it when doing the deal. Then Admin has to collate all that info, send the relevant forms to the relevant people to scan in so Govt and insurance/finance authorities can ensure its been done to their satisfaction and updating the computer systems that communicate with others including the DVLA to ensure you don't get pulled for having no insurance or tax.
Now some of this has been automated in some bigger companies but instead of a form the Salesman/Admin/Manager has to do it all online and get you to click your esignature. The process is the same and time consuming!
The other point was, in the old days we used to hide the admin cost in the price but these days you aren't allowed to. Everything has to be above board and costs seperated so you can see what you are paying for.
I think one of he only industries involved in sales to the public where you have more Admin to do, is the Insurance IFA industry, but again, Car dealers need specialists because they sell those products as well!
