These are great questions...the two Wallace Brothers have 6 stores between them to my understanding...They had about 5 Z06's at one point. Not bad at all considering how rare they are. Canadian cars are next to impossible to get. I was pleasantly surprised obviously when I found out!
It's a tough ride - try to stick with it.
Good luck and I hope it works out for you. Giving them a call may not be a bad idea...
Bob Wallace owns 50% of Gateway in Brampton and also owns Markville. Not sure which stores his brother owns.
