The car is not produced anymore, it has never been exported to NA, it does not comply with canadian regulations
Some quote I got, these are s14:
NISSAN SILVIA 1995 2 MANUAL SILVER US$ 6,000
NISSAN SILVIA 1997 2 MANUAL SILVER US$ 9,400
Misc:
NISSAN SKYLINE-GTR 1999 2 MANUAL SILVER US$ 44,000
MAZDA RX - 7 1992 3 MANUAL BLACK US$ 7,500
I found nothing about s15 but expect over 11k us for a 99 model and then you cannot drive the car in canada ...
