I bought my 99 C280 Sport back in March of 06 with 57k miles. It now has around 62k miles. So far I have replaced:

Belt Tensioner & Drive Belt - broke while driving
Crankshaft Sensor - broke, car would not start
Fixed leak in tranny, allignment, temperature control aspirator.

I still have to flush my break fluid. After looking through the car's books I can not find any indications that the car has ever been brought in for a service. So at 62k miles im woundering if it is time for a service and should it be a service a or b (whats the difference and how much do they cost?)

Thanks!
