Hi Julie,
Welcome, and you have not only found a great site, but also a great community! (you've probably already discovered).
I bought my L300 through Terra 2 about 3 years ago. Nice guys, smooth transaction, etc - but I paid a premium price for my van, and I was on my own with compliance, and the van was delivered to me as is - they are primarily importers. No preventative maintenance, no warranty - plus I had to wait 2 months for my van to arrive from Japan.
I suggest that you contact one of the preferred dealers here in vancouver, get a van with all the belts, fluids already done, and one with a warranty. It's a little piece of mind - go with someone with a good history at delica.ca.
Rising sun just got some new L400's

Also, Mardy at amazing autos has a very well established track record here.

And by the way, I recommend a crystalite roof for your kids.
