It is pricey. All worked out for the best, i contacted Car Giant, who sold us the car only a few weeks ago, and they were fantastic and agreed straight away to pay for it.
For their generosity and helpfullness i am going to put in a shamless plug for Car Giant in London, who we have bought both our last cars, including the RX300, which has been a great place to buy a car, and for the Lexus garage on Edgeware Road, North London, who are very courteous, looked after my pregnant wife very well when she brought the car in the for both the service and to look at the alarm, and cleaned the car gratis while she waited. The service cost was also very reasonable.
