I sent a bill of sale and a signed-off title to the buyer on May 1, 2013. On July 28, I ran a CarFAX on the VIN. The interesting part is that the CARFAX Price Adjustment is +$2,270, based on information available through CarFAX sources. The last entry was July 2011, and the new AC/Delco shocks and struts aren't on there, nor are the PowerStop brakes, nor the Timken front hubs, or any other improvements since June 2011.
I just ran yet another CarFAX (September 25 and got the same data, Price Adjustment +$2,270, "Certified One Owner," and no new data since June 2011.
The car is still in my name somewhere.
