i have heard that the c240 and the c230 are on their way out....and a new motor developing low 200HP is due in as the entry level SLK is expected to launch this summer. Both BMW and Audi have increased the size of their entry level engines...it only makes sense that benz do the same. If you are considering the c230 right now (which is a very good car)....make sure you get a decent amount off the price as you will see a dip in your resale value in the future.
