Responding to TexMex made me start thinking about when JW would have first seen the Mosler. He posted a photo of it on SM (A) on January 4th. The DMV lists the car as passing its emissions test on January 3rd in Derwood MD, months before SS hired JW. I just checked the arial view of the Autobahn parking lot and I FINALLY found where the photo was taken - in the Autobahn parking lot (B). You can see the very distinctive stripes to the starboard side of the Mosler (C), as well as the top of the address of 8260 Preston Ct across the road (D).
Given that the car registration seems to have expired and the emissions test is necessary to renew it, I would assume that SS was not driving it on a regular basis before January. Since there's no photo of JW driving the car, we don't really know if he did. I think that day is the first time JW saw the Mosler and if he and the car are involved in the crime, I think that would be the earliest a plan could have started hatching. Absolutely JMO, but I have a hard time believing the impetus for the crime was a ten year-old grudge, although it could have played a role.

ETA: JW again posted on SM about the Mosler on April 17th. Was SS driving the car without current registration or had he renewed it online and MD doesn't report registration renewals to Carfax?
