I would like to give terra2 a positive rating. However, I would like to first echo jfarsang's comments:

A note about this thread (rating dealers).
Although it's a good idea, I think it can also backfire on good dealers.
Reason being is that everyone is different, has different expectations and experiences at dealers.
So the ratings can go from one extreme to another.
I would hate to see a good dealer get shafted because a customer has higher-than-average expectations and rates the dealer unfairly.
It's just something that can't really be measured accurately.

I would also like to add that I think the negative experiences tend to surface more than the positive ones.
Anyway, I had a very good experience with Terra2. They were extraordinarily courteous, and I believe they worked hard to satisfy me. I believe that an important measure of how "good" a dealer is how they deal with the inevitable problems that come up, and again I am echoing the comments of others here. My first issue was that I bid on, and won a van at auction that didn't quite fit my needs. It was a late 91, but I soon learned that it didn't have the rear shoulder belts - a must for me and my family. Before the van even left Japan, they allowed me to switch the van they had committed to on my behalf for one that they had purchased for their own inventory - at no additional cost to me. There were also a couple of other small issues - like it was supposed to have an hot/cold box and didn't, but we agreed on a financial compensation and I was satisfied with this resolution. They seem to me to be just as concerned about their reputation, and about satisfying their clients as any decent small business.
It is true that bidding on a vehicle in japan is not for everyone. It's a bit of a leap of faith, and a long wait - but at the same time it exciting, and I kind of enjoyed the anticipation of it's arrival (a perverse pleasure). I waited about 2 months for mine. For both of the vans I was interested in (the one I bid on, and the one I switched it for) I had the photos, (measly photos), and the auction reports. One report was provided by the auction house, and a second report was from their (terra2) inspector, confirming the accuracy of the first and recommending a bid or not. I felt in both cases that these reports were trustworthy and accurate - I saw both vans once they arrived here.
My Van was in better condition than I had expected, in fact, it was as perfect as I could expect. I think it is better condition than my 2006 vibe! It also had a bunch of extras I wasn't expecting like 16" rims, extra driving lights, fender flares and a ladder.
In the end, after tires and maintenance, I did pay more for my van than some other dealers charge, however, I did get an exceptional van. I looked at a lot of vans on the lots and so many of them were just not up to scratch. I always climbed up and checked the roof and the back window for rust, and often found it (of course this was never disclosed). There were also many cosmetic flaws like dents and scratches, and bad interiors. So, I was very happy with the exceptional condition of my van, both inside and out and I feel like I got what I paid for. I take my van to CVI for their awesome mechanical care, the same shop used by the more popular dealers anyway.
I would definitely recommend Terra2, with the qualifications about the risks and waits associated with buying at auction (although they do often have inventory here too).
My last observation on this topic is that there is a LOT of mudslinging on the lots. I am always turned off by individuals that feel the need to prop themselves up by discrediting their competitors. I realize that this is a very competitive market now, but I prefer to deal with a company that doesn't engage this way.
I think I've rambled a bit too much. In the end it's about the van, and not so much the dealer. Look at as many as you can, and ask lots of questions.
