The total price including tensioner & idler which should be changed too for real peace of mind, seems normal enough - but you should also think about a new water-pump while you are at it because they are inclined to start to dribble at the age of your car and will probably need to be replaced soon. It will of course add to the cost, but will be cheaper to change at the same time as the cambelt than separately later. Aside from servicing, tyres etc, and with a little bit of luck, that will probably be all you ever need to spend on the car.
Great minds think alike,yeah i will do waterpump too-its a false economy not to-thanks
Ipurchased my is200 se auto from Lexus brighton a few years ago had servicing carried out by them always polite effecient,i definitley only trusted them at the time to do the cambelt+ it was 3 years ago but i assume their technicians are fully up to the job still paid around £500-550 so doesnt seem a bad deal .
