Renault's recent decision to axe UK sales of the Laguna and Espace (and the fact the company still hasn't decided how to replace these models), reminded me of something that Richard Parry Jones, Ford's retired engineering guru said at Autocar's 5000th issue bash earlier in 2011.

Parry-Jones said that a car manufacturer either builds budget cars in huge volumes or it heads upmarket. There's no middle way. For mainstream car makers, 'upmarket' might not amount to a huge sum. A decade ago, the then-boss of Renault told me that his biggest headache was the fact that Volkswagen managed to get a showroom price of around £1500 more for a Golf than he could achieve with a Megane.

That might not sound much, but over annual sales of, say, 400,000 vehicles, that's an extra £600m in the Wolfsburg bank account each year. Car makers are loathe to reveal the margins made on individual models, but I found out that a certain compact premium German saloon car returns an average profit of £5000 per sale, which is regarded as impressive in the industry.
