It's something you often see on the Motability scheme, when a facelift of an existing model is due to arrive soon manufacturers will often offer high spec models with very favourable low deposits. It helps them to shift the existing stock ready for the new models to follow on behind them. Works for both sides, to be honest. The customer gets a near top spec car for not very much money at all, while the manufacturer makes an easy sale of what would otherwise be quite a difficult car to sell without a significant discount.
