I traded my 2010 JSB 4LT GS for a 2011 JSB ZR1 in November of 2013 at Brian Cullen Chevrolet in ST. Catherines, On. The car was sold soon after to, I was told, someone in the Waterloo area. I have some interesting history information about this car (all good!!) for the owner if interested. The VIN 1G1YT2DW5A5103XXX. If you're on this forum and want to know about the cars history (at least until I traded it) send me a PM.
