I do not want or plan to rebuild the C6 it is in working condition. It's the e40d that needs the rebuild. 1400 seems to be the price of a second one some go higher. I never see them go under that.One was for sale for 500 but was stated as broken with out any details of what that meant or how long it has been sitting or where it has been stored. I may have to take you up on the phone number and yes it is touchy subject. This van is used for work not play and the down time was pretty costly on top of everything ells. So for something so simple as a filter and oil change for it to have turned into such a disaster I cant help but be a little ticked off.
