Interesting, thanks for the responses everyone.
jruz- What? You don't believe everything you read on the internet?

You might not recognize my name on this forum, as I sold my 4Runner just before YotaTech arrived, but I've been around in the 4Runner community for a while. I have some Canadian brochures (which aren't terribly specific, but they do give the models and the options- just not the technical details like what BigJohn mentioned) and I've spoken to some Candians. While it's possible that there was a TRD version, I'm pretty sure I would have heard of it by now. My guess is that any 4Runner in Canada that says TRD is a dealership special or done up by a 4Runner enthusiast. I don't mean to come off like a snob and I applogize if I've offended, but on this one I'm certain there was no TRD version. We definitely would have made a big stink about it here in the US if we had been denied the TRD version.
BigJohn- I agree with you on the Badlands seats! When I lived in Texas, I considered trading my '00 for an '02 Badlands- a dealership in San Antonio had purchased a BUNCH of them with less than 500 miles each. I went down and had a look at them... seats were much plusher. I liked the steel rims, too. Your mention of the washer fluid low light turned on a lightbulb somewhere WAY back in my head... I wonder if all models of the 4Runners had that? It might be a requirement in Canada.
lee- From what I've read and heard from people in the know, all Canadian Limiteds (in 99/00) had the rear heater, roof rack, sunroof, and locker standard. Those were all optional (but fairly common for the most part) in the US. I have some build sheets on 4Runners imported to the US and the only option that is rare of those was the locker- about 25% produced had it. But that's still a lot to choose from.
MTL_4runner- you bring up my number one concern. I wonder how easy it will be to service a Canadian 4Runner in the US- TSBs and such. The salesguy said that the 4Runner they had wasn't certified but that he would get it certified for me. At the time I didn't know it was a Canadian model- but I looked it up on Carfax. Granted, it has been here for several years, so obviously some service has been performed on it. Hell, if I can get a really good deal on it, I'll figure it out.
