Wiz, you're quite right. The model could only continue in its purest form, if equipment and staff continue to be replaced at intervals not exceeding their efficiency 'use-by' date! Don't know how that's going to pan out in relation to either equipment OR staff!!
Nomorecatering,
A little research would show that Jaguar are actually owned by Tata cars of India. So your choice would, in fact, be a valid two-company based choice and not relevant to this topic. Nice try though.
