Glad your cars working how it should have-I'm now an ex C300 h owner,lost confidence in the car with the amount of owners that have all the common hybrid related issues(and some other w205 ones too)add that to the lack of mb technicians trained to maintain/repair these complex cars I decided to cut my losses(only owned the car 6 months and in truth the C250 cdi would have been the wiser choice with little difference in running costs doing 12k in it annually).
My mileage is low but this works as a company car tax wise.
