Hi James, welcome to LOC, my advice for buying a is200 take your time and don't let your heart rule your head , there are plenty of nice cars out there so make sure the car you buy is the best that you can get for your money, .....the cam belt change is not only at 60k but also every 5-6 years , so if the car has say 80-90k miles but the belt was changed 6yrs ago it will need doing again, bottom suspension joints wear, brake caliper pins seize, but overall these car are pretty bullett proof if they have been serviced regulary, keep us posted how you get on with your quest, good luck.....
