My GS300 did 63000miles, just bought it 3months ago and is due for service in early jan, so i rang lexus dealer to arrange a full service, and they quote £565 which i feel is too much, for a car which got lexus service history, and last service was full service but have been told its due to change some plugs, its a 57plate, please can u advise as am new to the forum

Point of correction it's 63000miles not 630000miles

Please bare with me as I am new, just bought my Lexus gs300 and is due for service early jan, so I made a few phone calls to book the service and the cheapest I got is £565 because its in 630000miles. Please any advise
