I've been driving my RHD Delica for a few years now, the only issue is turning left in an intersection. Sometimes you just can't see around the vehicles facing you and you just have to wait. Not be able to see clearly if you need to pass, well, passing isn't always an option anyways with the small diesels.
Also, depending on where you live and what you get, insurance can be a nightmare!
I researched vans hard until I decided on which one would be the best fit, so I know very well that Delicas are rhd.
Yet, when I am returning north from Seattle and inevitably see a Canadian Delica heading south from Vancouver, I always find myself saying, "Hmm, cute girl driving the Delica".
Next month, "Hmm, cute girl driving the Delica".
Next month, "Hmm, what's up with all these Canadian cuties driving Delicas...oh yeah, duh, that's not the drivers seat..."
