Ford GT.
550 hp, stunning looks, fairly reliable (could be driven daily), built in the USA so you'll only pay GST when you import it, and quite rare. Easily modified if you're into that.
Actual cost for a $150K USD Ford GT would actually be about $197K CAD though, since the exchange rate has gone against the Canadian dollar lately.
$150K USD = $174,175.57 CAD
GST = $8708.78 CAD
PST = $13934.05 CAD
Air Conditioning Tax = $100 CAD
RIV Fee = $204.75 CAD
TOTAL = $197,123.15 CAD (roughly $175,000 USD)
So, if your budget is $175K USD, you'd be okay. If it's $175K CAD, you'd be hard pressed to do it.
