En Ontario, on doit payer HST. (13%) It's the same if you buy private or from the dealer.
I think $7k+HST is a great deal. That makes it $7910. Brand new from the dealer a base S would be ~$13k (normal price), and doesn't include the extra winter tires.
That's a nice $5k discount for 20k kms and -1 year from the warranty.
You're right though: no idea how many burnouts.
