It was yesterday and today only. It was at the national trade centre. They had two test tracks set up and a drive around the lakeshore. They let you drive the XLR, CTS, CTS-V, STS, DTS, SRX, and the Escalade. They even provided lunch.
I went to the same thing about 6 months ago.
Nice for the free dongle and lunch, other than that driving the cts-v was fun .
Have to say they have the same morons who work at dealerships there who do not know a damn thing about the cars other than what is printed on the window stickers.
