Winnipeg is not a terribly affluent city, has longer than 'normal' winters, and poor road quality. So unlike Vancouver or Toronto, exotic cars are few and far between.
That being said, last summer I saw an orange Gallardo a few times at a stop light near my apartment. The driver always drives off normally, then steps on it for a few seconds. The noise that comes out of the back of that thing is heavenly. A fellow with a new GT40 shows up to the local car shows sometimes. I've seen him drive up and park - albeit at low speeds. The best part is I then get to swarm over the car. Look under the hood, etc. That car is a work of art behind the firewall.
This might not count, but I've seen an Aston Martin V9 Vantage parked on my street a couple of times.
And then there's the 911's. Not really that exotic, but seeing a Turbo drive past was a highlight.
Oh ya, and when I was in Toronto on business, I saw and Audi R8 drive past going the other way. I had to look quick, but I saw it.
