Funny you should comment on the "vent windows" in the doors. Just this week Ive got new doors and they have been converted over to the one piece glass, looks much cleaner now I think.
Those vent windows were only on the very first models over here, after a year or so we then got the one piece glass like you guys have. Ive only seen a hand full of mazdas over here with them as well.
As for the rear, Ive just got to get my rollpan in and finish stitching up all the welds. Then Its time to strip the paint and get the bodywork and paint done.
Heres A pic of inside the tray, its going to change slightly due to the caddies being recessed into the tailgate, but that will just be a slightly boxed section.
You guys might get a kick out of the stock RHD as well... Mind the multicoloured interior ha ha.
