Newbee Canadian... Help :S

Yah... I really dont know anything about cars yet, but I hope to change that. Im definatly gearin towards getting a Prelude, 4th Gen, but I have a question I cant find the answer to. Im assuming its because I live in Canada, but what is the difference between SR, and SR-V? I have no idea but I am assuming that SR is the same as Si? I really have no idea though haha. If anyone could help me out that would be awsome, and what do you feel is the most KM's I should get on the car? Sorry I dont know miles, remember Im canadian, thanks in advance.

I'll assume the SR is the same as the Si in the states, and the SR-V is the vtec version with the h22.

Ok thanks... and with 1 mile = 1.6 km, whats the ceiling I should be looking at? I was thinking nothing more then 150000 km on it, which is pretty much 100000 miles. Any other info that I "should" know would be helpful too :) Ive read a ton in this forum and on other websites as well, but anything else you think isnt stated to often and I should know... and BTW, how much does a 94ish Si cost down in the States? Up here its around 12000, ew.

12,000 american dollars? that seems very expensive, you can get a 5th gen with decent miles on it for that, what is the american->canadian exchange rate?

XE.com says

1 USD = 1.37916 CAD

well a 94 si are appraised at 5610 here and that is with 100,000 miles and 4ws, thats about 3k less than what yours are going for.
