After last week's news that Renault is offering a free electric Twizy with its Laguna and Espace models in Spain, now comes the revelation that some Renault dealers in the UK are offering cars at cost price, plus £1.

According to The Daily Telegraph, some of the French carmaker's outlets in the south of England are letting cars go for the same prices as Renault paid for them in the first place. All the franchisees ask is that for every vehicle they sell at cost, the buyer hands them a £1 coin.

Dealer group Motorline, which introduced the scheme to buyers looking for new car bargains, said: "These cars are priced keenly to clear space for the new 13-registrations due over the next few weeks. Substantial savings are available."

The "cars at cost" idea is not original – US dealerships, which practice more aggressive sales techniques than their Brit counterparts, have long been offering some vehicles to customers at cost plus $1.

Now Motorline has adopted a similar business model, while stocks last. But the Telegraph warns that if the information is not already volunteered – as it should be – by sales executives, consumers need to ask for proof that they really are paying the same for these cars as the retailer paid the factory for them. Ask to see the paperwork, including detailed invoices, generated between manufacturer and dealer. And, if possible, get copies.

It's no secret that Renault sales have been seriously suffering in the UK but such a move is dealer-motivated, and will help businesses receive their volume-related sales bonuses from the manufacturer.
