@Capt-Lost. He is not talking about oil change and washing only. Full service means, they have to change lots of consumables including brake pads all type of oils, some belts etc. The cost will be around QR 1000/- but better to do it from Honda, as this still new car and you will be sure that everything is alright, as they will check it for you thoroughly. Off course it will cost you a bit higher than local workshop.
