I agree that the car is reliable, however you soon get the £1,000 back by getting fairly minor items sorted out, Items you might otherwise consider leaving with due to the cost of parts and labour. In today's money, £1,000 is not a lot of money, in particular where luxury brands are concerned.
Under warranty, I have had replaced both taillights due to condensation and one mirror that would no longer darken. As pointed out above by Tom, other brands may have refused to pay out and put these faults down to wear and tear, but mine were replaced without quibbling. And I got a free courtesy car. And my car got valeted while at the dealer. And I am still covered for 2 years.
