Also spotted a SG E93 with Michigan plates on the way home. Pulled up next to him on Lakeshore at Bay, and asked him where he was from (one advantage of having the top down). He said he was just back from Cali on a cross-country drive. I am super jealous.
Then an Aston Martin Vantage vert passed me on the QEW on the way home. He had the top down as well, but I had to keep up until he exited at Erin Mills. The Vantage is a gorgeous car.
