and that's great for you. really, the csx is an adequately performing fun car.
I think what you're failing to consider is the application of GTR's within their current context.
Supercar, no. But (being Canadian), you'll be hard pressed to find something that'll perform much better than a +/- 10k$ freshly imported GTR. That plus almost infinite mod possibilities for immense power, there is no wonder why these cars have such a reputation.
Due to this, and the fact that the US cannot legally import these cars, further perpetuates their cult status.
I don't really understand why you're bringing the NSX into your comparison as well. Apples to oranges.
You have to spend 3 times the amount of money to get into an un-molested NSX in the canadian market.
And even at that, put competent drivers behind the wheels of each car, and you'd have a pretty even match.
