It is part of its new Affinity Partners Remarketing Programme that it plans to roll out to other businesses and organisations.
Almost 12,000 Round Table members are now eligible to purchase nearly new cars at preferential prices direct from the company.
The company supplies vehicles to the self-drive hire industry, many of them on buy-back programmes, with the cars returning to Camden at the end of their fleet life.
They are then remarketed through a number of disposal channels including trade sales to Camden Motors Group dealerships, sales to other dealers, and sales to the wholesale trade and auctions.
Now, with the launch of the Round Table of Britain and Ireland Privilege Car Purchase Scheme, nearly new cars are available to members at special prices before being made available to the trade.
Business development and marketing director Jeff Peyton-Bruhl said: 'We have been investigating some new routes to market for our nearly-new ex-rental cars and the thought came to me of selling the vehicles at preferential rates to my Round Table colleagues.
'The idea then developed to Camden Corporate Fleet Services establishing similar schemes for the staff of our major customers and then on to the staff and members of other major affinity groups.
'With at least half a dozen major affinity groups waiting to see the launch model, it is easy to see how this idea could really catch on, especially with the HR departments of many UK companies consistently looking for additional staff retention and recruitment ideas.'
Almost all cars under the scheme will be ex-rental cars, typically up to seven months old with about 11,000 miles on the clock.
