I am considering the purchase of a 2000 C280 Sport model 4 door sedan. It has 47,000 miles on the clock - just dorve it today, very nice condition in and out. It's for sale at a BMW dealer and was traded there for a new BMW. The Carfax report is clean and it's had only i owner since purchased in 2000. Are ther any problems to watch out for with this model and year? Thanks for your input.
